Keeping up with the “I post what you post, you post what I post” paradigm, I feel obliged to inform you that MySpace has launched their development platform which is based on OpenSocial API.
As opposed to Facebook, MySpace are going to have two or so month lead in period, so to allow fair play for all developers. Until that moment has passed no application is allowed to have more than ten or so installs.
A little bit worrying comment is this:
