Forgive me if this has already been covered, but nothing showed on search, so I am going to assume it has not. If it has, and I don't survive the ensuing inferno, please dispose of the body in an eco-friendly fashion.
Recently it seems that Facebook, Mememespace et al have been taking over teh interwebz, and I confess to having an account on at least one such site. A new development is underway which will take social networking to a whole different level.
Enter Rocketon. I read about it on the BBCNews|Tech page and went off to see their site. There's not a huge amount their site, in terms of detail, but the BBC article is very interesting. It has huge potential as an idea.
The article also discusses PMOG (or Passively Multi-player Online Game) which is a very odd idea. Quirky, I rather like it.
