Aardvark is a search engine founded by ex-Googlers, that uses social network power. It is not based on information created by users and than indexed. It is distributing the query among your afiliates and their afiliates, who find themselves good at different fields - if you’re lucky you might get the answer. Idea is not stupid, or rather decent. User can ’search’ by using IM, e-mail, SMS or Twitter.

To increase probability of being answered you should take care and gather as much friends in the service as possible, which is a little bit hard especially at the begging after releasing public beta version. But there is an option to grab the contact list from Facebook connect.

After typing in the query the algorhytm searches for person that is most probable to have knowledge about what user is aksing. Than user just have to wait for the answer. Basis for poining on specific user as the one who has appropriate knowledge is the fact that he introduced himself as having knowledge on particular field, coming from specific region or interested in something user asked about.

It looks like this sort of human powered search is one with completely new approach. It is interesting how many degrees of affiliation can be potentially used. However it can be a great source of help and really practicl information in some cases. Except for that Aardvark looks like it is going to be not only the source of information but also sort of place to make friends and have fun.
