In some ways I think Americans are cheap. I'm imagining a paid FB-like service in the range of $5-10/mo, considering ISP packages can easily run up to $80/mo, and a FB-like site should ideally only consume a portion of that. But I think you really need to re-think the core concept of a social platform. Can't find the comment on HN, but someone a few days ago mentioned: social platform vs. social technology. A social platform is likely to be closed; Facebook only wants you to communicate via Facebook, same with Twitter, G+, etc. If you decide to email your friends instead of using FB, they lose out. A social technology, however, doesn't care about other providers as much. Think about a telephone company. They obviously want you to use their service, but they don't care if you call someone who has a different carrier. Likewise, they won't listen in to the content of your calls to tailor their service to you, because them providing you phone data and the contents of your calls are completely orthogonal. Try thinking along the lines of a social technology, rather than a social platform. E.g. my friends want to put together a movie/pizza night so they go to Facebook to create a poll to decide on a movie and pizza toppings. Why can't that be part of an SMS standard? It seems to me like SMS has a lot of potential for future iterations. Right now you can send texts and images to one or more people. Why not bake in other features like polls, appointments, etc. It truly has frustrated me that my friends will use Facebook to organize something that could easily be done over SMS if it just had a few extra features.
