习惯而已

首发时间:2009-03-06

为什么机场的安检要这么繁琐?为什么在中国不允许收看国外的电视?为什么房价这么高?为什么公车站浪费你这么多等待时间?为什么交通这么堵塞?为什么电脑和手机通话还要收钱?为什么廉价的教育没法普及?。。。。

这个世界有太多的问题、太多的不完美。正是这些问题的存在,让我们的生活不够美好。而人们又很愿意为了改善生活付钱,正如你会为了购买热水器而付钱,一年后又会为了维修漏水的热水器付钱一样。于是,理论上,我们能看到的任何一个问题都是一个创业的机会。创业的本质也就是不断解决人们生活中的问题。

如果一个人平时很喜欢去解决生活中的各种问题,那么,这个人也应该很容易接受创业。对于这个人来说,创业只是一种生活习惯的延伸。

回想起来,我从小就开始做题目,做过几万道考试题,解决了几万次书本和试卷上的问题,却一直不敢去解决生活中的问题,直到创业之后才发现,解决问题本来就是每个人生活的一部分,也是每个人或多或少都有的一种习惯。所以,每个人都有潜力来创业。但是为什么我们一直不敢呢?

是不是我们的思维模式出了问题?

在学生时代,“创业”这个词就一直是一个被神化了的词。出现在我们面前的新闻都是xxx拿了几千万美金的风投,yyy一年内实现了几亿美金的营收,要不就是北大学生卖猪肉的笑料、复旦学生搞废品回收站的谈资。。。。难道只有这样的极端案例才叫创业么?与其说创业被神化,不如说是被扭曲、被误读了。

google是创业、facebook是创业,但是,如果我们把创业看成“搞另一个google、facebook”的同义词,那就是混蛋逻辑了。google和facebook在所有成功的创业案例中连0.0001%都占不到。更多的成功创业者,他们做的只是开餐厅、卖床上用品而已。日本去年最冷门的创业家,只做了一个向用户提供机场空余停车位信息的手机服务,就赚上百万一年;美国的37signals只向公司提供付费的在线协作系统,也坐收几百万美金一年;广东一个卖psp和GBA游戏的小伙子,通过线下分成的模式,一年也净赚300万人民币。他们没有风投、没有几个Billion的估值,却实实在在地为客户解决真实的问题、创造真实的价值、并且每时每刻都在赚钱。99.9%的成功创业家都是这样的无名氏,可是很少有人知道他们,因为大部分媒体只发布劲爆、极端的新闻。

前几天去北京的飞机上,和shute、wangtao开了个空中yy大会,聊起了减少公交排队等待时间的一个生意,算了一下,光杭州一年就能赚上千万。回来的飞机上,在登机口看到一个巨pp的空姐,想到国内那么多有钱或有才的单身汉终身无缘和美女约会,于是又聊起了另外一个美女约会租赁的生意,聊一小时之后,又一个详尽的商业计划出炉了。。。。

当然,计划终究只是计划,到底能不能做出来还要看团队的执行力。不过我相信,如果我们仨每周出去yy一次,出几个可行度很高的、低成本的、低风险的商业计划,是没有任何问题的。这不是为了炫耀什么,只是想说,所谓的创业,就是从现实社会存在的问题中看到可以盈利的解决方案而已。创业真的不是那么遥远。

Javascript Widget入门解析

首发时间:2009-02-07

收到读者的来信,希望知道采麦的Widget是怎么做出来的,突然想起当年我第一次写widget代码的时候,也是满世界找不到一个简明实用的教程。于是做个总结,也许更多人可以用得到。

复习一下两个js函数:

js可以动态生成网页代码,比如:

document.write(‘<div id=”photo”>123</div>’);

这段代码可以让网页里显示出一个叫photo的层,里面还有数字123。

此外,js可以动态改变网页内容,比如这段代码:

document.getElementById(‘photo’).innerHTML=’abc';

就可以让这个photo层里显示abc,而不是原来的123了

别看这么一段小代码,其实这就是整个widget的核心了

技术原理:

widget有3个重要部分组成:数据、外壳、脚本。

  • 数据:就是你希望显示出来的内容,比如你要显示flickr上最近的照片,那么照片就是数据;
  • 外壳:就是容纳数据的容器,比如上述照片,你把他们包裹到一个叫photo的div里,那么这个div就是外壳。
  • 脚本:脚本的作用是生成外壳,并把数据填充到外壳里,主要就是js代码,当然也可以带一些css

所以,理论上,一个原始的widget代码应该是这样的:

//js脚本生成外壳photo
document.write(‘<div id=”photo”></div>’);
//js脚本把数据abc填充到外壳photo
document.getElementById(‘photo’).innerHTML=’abc';

是不是很简单?是很简单,可惜太长了,于是把上面四行代码的中间两行提取出来,复制放到一个wjs.js文件里:

//js脚本生成外壳photo
document.write(‘<div id=”photo”></div>’);
//js脚本把数据abc填充到外壳photo
document.getElementById(‘photo’).innerHTML=’abc';

这样只需要调用一下就可以使用widget了:

<script type=”text/javascript” src=”wjs.js”></script>

好了,到这里你已经学会了最简单的widget制作,快去实验一下吧。

基础进阶:

那么,如果数据不是abc怎么办呢? 很简单,把数据独立出来就可以了。我们改造一下wjs.js代码:

//利用js建立photo层,生成外壳
document.write(‘<div id=”photo”></div>’);
//js填充数据:
document.write(‘<script type=”text/javascript” src=”widget.js”></script>’);

数据就在widget.js里,我们分析一下其代码,只有一句:

document.getElementById(‘photo’).innerHTML=’xxx';

这样的话,要改变数据,只需要把widget.js里的xxx换成任何内容即可,而无需改动wjs.js

中级进阶:

如果要自动动态改变数据xxx,只需要把widget.js也做成动态的,以php为例,首先把wjs.js修改一下:

//利用js建立photo层,生成外壳
document.write(‘<div id=”photo”></div>’);
//js填充数据:
document.write(‘<script type=”text/javascript” src=”widget.php?user=howard></script>’);

注意里面的widget.js换成了widget.php,后面还跟了一串变量,这样就可以显示为howard量身定制的数据了,看看widget.php的代码:

<?php
Header( “Content-type: text/javascript”); //声明文件类型为js
$user=$_GET[‘user’]; //读取user变量 (howard)
echo “document.getElementById(‘photo’).innerHTML=’hi, my name is $user'; “; //输出动态内容(hi, my name is howard)
?>

到这里,我们已经可以根据不同变量来自动显示不同的数据了。后面就很简单了,把widget.php任意改造,读取数据库,可以输出各种各样关于howard的数据。

实战应用:

事实上,实际应用中,wjs.js也被改造成了动态文件,比如wsj.php,这样你的用户howard只需要在其blog里插入以下代码,就可以真正实现个性数据调用:

<script type=”text/javascript” src=”http://domain.com/wjs.php?user=howard”> </script>

wjs.php的内部代码是这样的:

<?php
//声明文件类型为js
Header( “Content-type: text/javascript”);
$user=$_GET[‘user’]; //读取user变量 (howard)

//利用js建立photo层,生成外壳
echo “document.write(‘<div id=”photo”></div>’);”

//动态调用widget.php
echo “document.write(‘<script type=\”text/javascript\” src=\”widget.php?user=$user\”></script>); “; ?>

这样,widget.php收到了user变量之后,就能显示出howard的个性数据。

先写到这,大家可以先回去测试一下。真正能用的widget,代码和上面有很大区别,但是原理是相同的。

社会化媒体营销的两个小实验

首发时间:2009-01-21

实验一:通过奶粉钱把吐司网的一个作品做到了QQ书签的首页,结果如下:

  • 总共收藏超过26000(两万六千)人,而且在QQ书签的首页挂了24个小时;
  • 为了保证国内访问量的精确统计,除了google的analytics以外,我还自己做了一个后台统计,来一个ip加一次
  • 通过QQ书签带来的访问小于2000次(两千次),也就说93%以上的收藏者居然连看都没看就收藏了!!
  • 由此引发相关的社会化传播为零,因为google搜索该标题没有发现任何转载。

实验二:同一时间,我最近的一篇文章上了Del.icio.us热门第一页,结果如下:

  • Del.icio.us收藏113次,Del.icio.us过来的直接访问者600个
  • 引发相关的社会化转载最高时刻超过100次,包括FriendFeed, twitter, 也包括直接爬取社会化数据的网站(比如popurls.compopacular.comtheweblist.net等,见下图),这部分带来的访问量超过1000,高于直接从Del.icio.us过来的点击,其中尤其以popurls.com为甚,光popurls.com就已经超过了Del.icio.us
  • 除了英文国家外,这篇文章之后还被Gigazine翻译到了日本,然后被Livedoor转载,相关的后续访问超过五百次。
  • 因此这篇文章的关系,也使得我最近的其他几篇文章被日本读者和韩国读者翻译成了他们各自的语言。

实验结果很明显,在只考虑访问量增长的前提下,QQ书签营销的杠杆效用只有0.07倍,而del.icio.us的杠杆效用是20多倍。这就意味着,在相同收藏人数的前提下,del.icio.us的效用是QQ书签的280倍。虽然用户群体不同,但QQ书签和del.icio.us都是社会化书签,具有一定的可比性。

不过,QQ书签的流量虽然很大,实验结果表明其“社会化”还是流于形式,如果无法形成有效的社会化传播,那就称不上真正的社会化。通过奶粉钱的几十次实验发现,无论收藏多少万次,QQ书签过来的访问数一直都在收藏数的10%以下,这个结果完全在我意料之外(以前老觉着上了QQ书签首页怎么着也得创造个百万级别的访问量吧。。。。),也让我对社会化媒体在国内发展的模式感到担忧。

后话:

不过,QQ书签在不断进步,很多人都不知道,在2009年1月18号以前,QQ书签的热门收藏里80%是美女、露点、女优、免费A片、龌龊走光等“低俗”话题,而且排名也有漏洞,被奶粉钱利用了很多次。1月18号以后,被整改的干净了很多(不知道是不是“低俗”网站被暴光的缘故),排名规则也更加优化了(估计是被奶粉钱搞得发飙了)。至于之后怎么走,真正让它社会化起来,暂时我也没什么想法。

Why is Economic Recession Good for Startups

首发时间:2009-01-16

Weaker Competition:

Many big companies are struggling with laying off employees, cutting off secondary product/service, rebuilding management structure, asking for cash investment…..but definitely not going to release new product or better service very soon. Well, this is your chance to sneak into their market.

Lower Cost:

When people get unemployed, even students from great schools and managers from big companies are considering to work for small startups with discounted salary, which rarely happened in the past. Stuff like office, server, food are also cheaper than before.

Better Plan:

While VC is holding back their offers carefully in the recession, it’s more difficult to get fund with a lousy business plan, especially those without a clear revenue model or healthy cash flow. While your business plan is revised again and again but still get cold-shoulder from VCs, it’s more likely to survive in the real business environment.

Fairer Chance:

Well, we all say 9 out of 10 startups are going to fail within 12 months. It’s true that small company has high risk of failure, but after Lehman Brother fell apart, Merrill Lynch got sold, and auto industry monsters kept crying for help, it’s pretty clear that no company is safe in this world, and size definitely can’t determine the fate of a company. I’m sure people will tend to have a fairer attitude towards small companies.

Tighter Pocket:

I have a friend getting >10,000 dollars a month as revenue from his online business. Pretty good for startups, isn’t it? But what makes me sad is, he spend 10 times more money every month, 90% of which is for senior management’s salary, while the job of those seniors is just flying for coffee meeting once a month. It’s never too late to watch every penny in your pocket, dude, no matter it’s recession or not.

7 Steps To Build A Better Blog

首发时间:2009-01-13

1. Create Value:

Whatever you write, remember to bring value to readers. Just saying Myspace sucks can’t make your a good writer, since there are over 1 million people already knowing this conclusion earlier than you. Just saying viral marketing is amazing can’t make you a great blogger either. Say something more to make us know something fresh, or, to save our time, or, to create other value.

2. Focus on your own industry:

I can’t remember anything you write if you write about everything. Focus on one industry you’re interested in, man. Beer, Mac, Black-Hole theory…… anything would do, as long as you’d rather cut your sleeping time and sacrifice your dinner to make yourself know it better than anyone else.

3.Blog is not twitter:

Blog is blog, but twitter is another thing. Don’t make your blog into another twitter. I’m not really interested to know what you had for lunch or which brand of soap you bought unless you are Charlize Theron, and 10 posts a day makes me doubt whether you are a blogger.

4.Write drafts:

When you think of some new ideas, put them into drafts as soon as possible. Finally you will find your drafts full of great materials to make a great article, and this is how other Blogger’s great articles are made.

5. Appearance matters:

Just as a great pianist needs a gorgeous concert hall to show his best performance, you need a suitable appearance to make your blog looks great if you believe it is great. Pick a clean theme, use related pictures, insert sharing buttons…and more.

6.Share:

Leave a full link when you quote another blogger’s post, and they will thank you very much and probably do the same thing to you in the future. It’s a small world, and readers won’t forget you just because you refer them to read another blog.

7.Hold on, man:

It’s a lonely and boring job to write blog when no one notice you. Don’t give up if you believe your posts are creating value to the society. Check your blog system to make sure the SEO part is well done. Hold on and keep writing. If you are still lonely after you write 50 posts, leave your blog address here, dude, and I’ll be the 1st one to make you not lonely anymore.

Practical Tips for Google SEO

首发时间:2009-01-10

Never underestimate the power of SEO. It’s the most effective & healthy way of marketing online. Although Google is constantly changing its algorithm of search ranking, but some basic rules for SEO still works at least now. Here is several tips from my own experience when I was in charge of the promotion for Tucia.

Commitment:

Pay money and extend your domain expiration time to 5 or 10 years later, so that Google won’t easily put you into the list of temporary spamming & cheating sites.

80/20 Rule:

20% of your keywords bring 80% of traffic. Give up all the other keywords except these 20% most important ones. 3~5 keywords would be the best. Focus on them.

Forget 6%:

Adjust your content, link’s TITLE, image’s ALT and everything else to high light your keywords. Don’t be afraid of too many keywords (forget about the 6% density limit), because you’ll never have enough high keywords density in a readable text.

I’ve seen a very stupid personal site with lousy page TITLE, DESCRIPTION, META, and shitty codes, but standing right on the top of Google search results. The only reason is ultra-high keyword density which I can never achieve when I try to make visitor enjoy reading it at the same time, for God’s sake.

Avoid Duplication:

Every page must have a different TITLE and DESCRIPTION and also different content text, unless you want Google to put you into the list of trash-producing sites.

Cross-Level Consistency:

You need to make Google believe that you page is highly related to the keywords, which can be simply done by putting the same text in different levels of the same page. Such as link TITLE, link TEXT, image ALT. For example, this text link to abc.htm:

<a href=”/abc.htm” title=”keyword1-keyword2″>keyword1-keyword2</a>

and this image link to abc.htm

<a href=”/abc.htm” title=”keyword1-keyword2″><img src=”/abc.jpg” alt=”keyword1-keyword2″ /></a>

Remember you have to put keyword1-keyword2 in the page TITLE of abc.htm

IF you can change the page file name of abc.htm to keyword1-keyword2.htm, that will be best:

<a href=”/keyword1-keyword2.htm” title=”keyword1-keyword2″><img src=”/keyword1-keyword2/keyword1-keyword2.jpg” alt=”keyword1-keyword2″ /></a>

Social Media Effect:

I found it by chance that a high rank in social media (e.g. Digg & del.icio.us) will prominently make your rank higher in Google too. I send Tucia to a low-cost social media marketing service, which helped me to get 600 diggs & 300 del.icio.us bookmarkers in a short time. In 72 hours, I found Tucia climbed to Google’s 2nd page from 5th page with the same search keywords.
