Facebook uses more than just PHP it uses a lot of C++ components as well, Google Python as well.

Wow, CSS is not there.

Can't program using CSS. Probably why.
Way I see it anyway.

http://trends.builtwith.com/framework

Shows the frameworks so not all the coding behind it but it's very interesting.

Also if you want to see the technology profile of a specific site then you can do this:
http://builtwith.com/nbcsports.com

Just use http://builtwith.com/ and then add the site that you want to know more about.

Stack Overflow is also built in .NET and it's in the top 100.

Nice list, few things I've read about online, but feel free to correct me:

2. Facebook – PHP

It is worth mentioning that Facebook have been writing something very similar to HotSpot (Oracle's JVM).

Must say when I heard it I thought to myself, wtf, why not move to Java/Scala then, but their code base and internal skills must be strongly geared toward PHP at this point.

3. YouTube- Flash, Python, Java

InfoQ had a talk with the main engineer (or maybe it was a PM or VP can't recall exactly) of YouTube about two months ago.

They started out with Python. He said it is mostly the same now with a lot of C++ and some Java now.

9. Twitter – Ruby on Rails, Scala, Java

They've completely dropped Ruby quite a while back if I'm not mistaken.

At this point they are running completely on Scala/Java...

You're mistaken. They have not dropped RoR all together.
