HowDoYa.com - Learn how to do anything!

If you need to learn how to do something, you might find it worthwhile to take a look at  HowDoYa. It's a search engine based on Exalead, which is interesting enough. Basically you just ask how to do something - like 'whistle' for example. The engine goes off and finds pages that give you that sort of information, and it also provides various ways of narrowing the search down, such as 'what do you need, who can help, why do it and where should you go'.

It's currently in beta, and is scheduled for a full release on April 1st, which is a very brave date to choose!
