Facebook: The New Google?

For many years now, I've thought of Google as top dog in the software world. But Facebook is challenging that. Yes, the frequent UI changes are odd, but the back-end tech is innovative and impressive. Talk about scaling: hundreds of millions of users. Daily number of writes is probably at least that. Daily number of reads is probably a couple of orders of magnitude higher. Hell, just getting all those email alerts out is impressive.

They're pragmatic: they use everything from PHP to C++ to Erlang (the billion-msg-a-day chat server), and they open-source a lot of stuff.

Freedom to choose the right tool instead of the popular one: priceless.
