you want a social network that i would use.
first let me make my own page, give me a template to base it off of if i want, or let me code the full html if i dont.
second, if my page causes eye cancer revert it, punish morons for ruining your service.
third. expand on things like google hangout, its a great idea, but not well implemented. let us create a forum or group pages, and in those pages, people we trust can join in on a group chat. think of this like a meeting place, people come and go, not something you set up and everyone has to be there right now or not at all.
fourth, give us freedom, dont make changes to design, and don't be stupid, facebook works for a reason, don't shy away from it just because, innovate and make it better.
