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.
