Hey Osama, oh yes its a very important question :)

The reason I started Jawab.pk was because we didn't have a central place where people could get answers to all the common problems we faced. You could normally do a Google search for a problem and chances were you could either something ranging from nothing relevant, to a lot of links discussing the matter and reaching or not reaching a conclusion/answer. We had gupshup forums, stuff on facebook/twitter (and twitter is pretty effective too) and then we had closed groups for example my own university's alumni group on Yahoo where we always had lots of valuable knowledge but which unfortunately was closed to the public.
So yes the idea is to have a central place where we have solutions to problems that people face pretty commonly. Our first "success story" was this question:
http://jawab.pk/q/how-get-domicile-certificate-in-lahore-whats-its-procedure/791 where the user actually found Jawab searching for "Domicile in pakistan" on google (we already had a question about it but it didn't have a satisfactory answer). Then she also happened to ask on another forum where she got an answer. AND one of our users managed to search the answer that SHE got on that forum and pasted it as an answer here (of course citing that as source). She then returned and as comment posted her own experience of getting the domicile. So, this is something that will help everyone in the future and its what Jawab.pk aims to achieve :) We're already getting many hits from google from people searching for Domicile in Lahore.
I think I might have digressed from the question :P But, the "Guides" section on Jawab.pk aims to achieve exactly this by creating proper Guides for really important questions. While for users to best utilize Jawab.pk they can ask about similar problems that they would be having and they can help with their experiences :)
