A dream I had last night was for a social network based on the deep but brief conversations we have in park benches, club toilets, hospital waiting rooms. Where we are totally open somewhat vulnerable but free from commitments. Think about the first conversation you have had with a friend, often it's the most revealing or deep one you may have.
Somewhat anonymous, short in time, one to one, with the potential to connect afterwards on outside channels. Possibly only one conversation a day allowed, and possibly only available to pre set contacts.
