Slightly off topic. I liked the ask.com idea for a bit of fun, however obviously it doesn't work now. I thought I'd type some questions in to see how well it would have responded... answer is crap totally useless. "how old is the queen" brought up a load of stuff about who she was. How to boil an egg, a few adverts nothing much else... however I did find a new site...
http://www.kgbanswers.com/I have no idea about scrapers and API's etc, maybe James can answer. But it seems really good. Here are some slightly open questions with great answers. Just the first three I typed in.
