Facebook is looking at adding virtual currency to its social networking service..
I have been interrested in virtual goods and services for quite some time now. Some really interresting links with regards to social networking and mobile services.
Virtual goods provide an alternative to advertising revenue stream. Most social networking services introduce some sorts of virtual goods - these usually go by micropayments via premium sms through the mobile. Now.. the good thing about virtual currency is that it brings element of fun into the game, the user does not think twice about paying as he would with real money :)
So we have, social networking services and virtual goods, mobile servies, services with virtual currencies - what be interresting to see a single services blending all these together!
