I can't exactly describe to you those objects in the photo above other than to say they are "servers." I think.

Let's be honest: very few of us can describe servers on more than a surface level. So let your mind be blown by this article (click photo) from an interesting website I've never seen before. Learn about Facebook's 30,000 servers, its 80,000,000,000 stored photos - not a typo - and the fact that it serves up 600,000 photos a second.

What?

The reality of the situation is that there are only about 12 truly important websites left in the English-speaking world, and Facebook is five of them: the world's leading photo site, a leading if crummy webmail site, the leading sharing site, a leading chat site, and of course the leading microblogging site.

Interesting chart and article. Talk about coming far and fast...
