Say you wanted to find out who worked at google and had a blog.

You'd ask Google, right? After all, they're the masters of search, they own so they know something about blogging.. You'd think they'd be able to tell you off the bat who of their employees blogs, right?

Wrong - they resort to doing google searches to discover the answer.

One enterprising person paid US$100 for an answer from Google Answers on this question, and also bloggers from yahoo.

I've not seen google answers at all before. I'm quite impressed by this -the answers are made publically available, and they tell you what search terms they used, so you can replicate/extend their results yourself.. Fantastic!
