When I say "how" I don't mean are you going to use OpenSocial or anything like that. I mean when you implement it, how are you going to make it useful?
I don't mean to be coy, but it comes down to giving people something that 1) removes, transfers, or simply defers pain and 2) simply increases happiness.
I would think that's useful in some way to some people at least some of the time.
On a plan to make the social aspect work, is there a finite list of ways to choose from? I don't believe there's really only one way. It definitely seems that "social networking" could have a negative effect on my plan yet I hope to do things a little differently.
There will be some socializing benefits.
