As you can see, it doesn't really matter what you choose; all of these sites have lots of traffic, but are based on very different technologies.

blocks|key|168046|text|在社交网站中，最重要的是后端，因为大多数瓶颈都来自后端。您可能需要考虑No-SQL数据库。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|168047|168048|Facebook和Twitter使用Cassandra|unordered-list-item|offset|length|168049|LinkedIn使用Voldemort|168050|168051|还有一些其他的，比如：|168052|Sourceforge.|168053|CouchDB|168054|

What matters most in a social networking sites is the backend, since most of the bottleneck will be from there. You might want to consider No-SQL databases.

<ul>
<li>Facebook and Twitter use <a href="http://incubator.apache.org/cassandra/" rel="nofollow noreferrer">Cassandra</a></li>
<li>LinkedIn uses <a href="http://project-voldemort.com/" rel="nofollow noreferrer">Voldemort</a></li>
</ul>

There are a few others like:

<ul>
<li><a href="http://hypertable.org/" rel="nofollow noreferrer">Hypertable</a></li>
<li><a href="http://www.mongodb.org/" rel="nofollow noreferrer">MongoDB</a>, used by Sourceforge.</li>
<li><a href="http://couchdb.apache.org/" rel="nofollow noreferrer">CouchDB</a></li>
</ul>

As for the programming language, as others have said, it does not matter that much. But if you really can not decide, you might want to consider a non-blocking webserver like <a href="http://www.tornadoweb.org/" rel="nofollow noreferrer">Tornado</a>.

blocks|key|167369|text|选择哪种脚本语言并不重要，只要大量使用memcached即可。拥有正确的缓存层次结构是必须的。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|167370|entityMap|0|LINK|mutability|MUTABLE|url|http://memcached.org/^0|J|9|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

blocks|key|167393|text|归根结底，这是个人喜好的问题。Twitter使用Ruby+on+Rails。维基百科在PHP上运行。Reddit使用一个名为web.py的Python库，但最初它是用Lisp语言编写的。我会说选择你最熟悉的技术。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|167394|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

At the end of the day, this is a matter of personal preference. Twitter uses Ruby on Rails. Wikipedia runs on PHP. Reddit uses a Python library called web.py, but intitially, it was written in Lisp. I would say pick the technologies you are most familiar with.

As <a href="http://www.joelonsoftware.com/backIssues-2006-09.html" rel="nofollow noreferrer">Joel says</a>

<blockquote>
 People all over the world are constantly building web applications using .NET, using Java, and using PHP all the time. None of them are failing because of the choice of technology.
</blockquote>

Choose whichever of the "big 3" (.Net, Java or PHP) that you know best - these technologies are known to be scalable, the real question of whether or not your site will scale is how the site is structured and the quality of the code - using whichever framework you are most familiar with gives you the best chance of achieving that.

Technologies, techniques , 

<ul>
<li>research what other scaled sites have used and done and what the problems they had were less than he successes, there are podcasts on iTunes, talks and interviews on Youtube</li>
<li>look at industry best practices and follow them to a degree</li>
<li>don't take peoples word for it, make sure you see the problem or the success as opposed to the pr glitz about it</li>
<li>avoid obvious things that do not scale vertically or horizontally, database connectivity, sessions - cookies and the like</li>
<li>look at nosql storage as an sql alternative less overhead but less functionality</li>
<li>take care when looking at the language/framework. frameworks come with lots of baggage you do not need, they speed you up initially and slow you down eventually, i.e. you spend more time hacking the framework than building the site, same with languages does it do what you want rather than be trendy, cool to programme in etc.</li>
