Multany, it seems that the question is about sites in general.. talking about this very site I agree with you.

I think - yes, but in my opinion one should take it as a possible lucky chance but not as the main aim.

yeah,if ur lucky :p

the answer is maybe "yes" maybe "no". i cant say no because there are many people out there started their friendship on the net, and i cant say yes because i havent found it yet.
