A valuable exercise, I think, would be to figure out what parts of a social network you could make monetizable without ads. Facebook et al have everything under the sun but not all of those features are monetizable (arguably some of them probably aren't worth the squeeze) I think a great example of a part of a social network that would be good is event organizing. Partiful I believe is attempting to make money in that particular space by offering paid super-user features for higher-volume party promoters and the like.
