Find a friend by interest

In order to find the person I need by tag on Habré and chat with him, at least you need to go, for example, if I am looking for interests on Jquery, to habrahabr.ru/tag/jquery/people and look for this person there. If on interests on PHP - that habrahabr.ru/tag/php/people , etc.

Is it possible to make the search go on several interests (or key words entered) reflected in my profile and find the people I need (that is, with interests similar to me)?

So I can solve my problems faster, much faster.

Thank.

Please do not send to Google. I start asking for help from people only when I myself or through my friends cannot find information on my subject.
