Let me clarify:
Platonic friendships are great.
Its not that GS is such a place that talking to someone is a big no-no. Its more that there are all kinds of people on here, married and not married. Its a forum for discussions on a million topics but its not a matrimonial site. You talk to people on here at your own risk and cannot be mad when and if someone turns out to be different from what you thought. Why? Because the purpose is not to hook people up.
We have a thread for that going in Weddings right now and there are other websites dedicated specifically to this goal like Shaadi.com, Mehndi.com, etc. I believe Shaadi.com can even verify certain important of information about their members like education and so on if they choose to do so to boost credibility of a member.
