I've been so-so about the Wolfram|Alpha hype, but it finally launched and it's definitely neat. Comparing it to Google is semi-ridiculous as Google uses structured data and “facts” only as an afterthought.

The servers are taking a beating right now, but here are some queries that were interesting to me:

A lot of data I encountered is old-ish – a lot is from 2004 -- which I think says more about the crappy state of authoritative structured data than Wolfram|Alpha itself.

I think the most exciting thing about Wolfram|Alpha is that it's intriguing and useful enough that it may encourage more organizations and individuals to make their current data available and keep it up to date. Which would be a huge benefit to everyone.
