hi there,
we just launched the open beta of Myrl (as in My Real Life), a cross-world social network for avatars where you can keep up with multiple virtual worlds and avatar accounts from a single dashboard.
We are basically building a layer on top of each virtual world, with the ultimate goal of linking them up to create an integrated playground with endless possibilities and applications.
This first release is the Social Gateway for Virtual Worlds and connects avatars from 19 worlds such as Second Life, Openlife, Google Lively, Entropia Universe and There.
Future MYRL releases will be focusing on mobile virtual worlds, cross-world gaming and virtual goods trading.
If you want to give it a go you can signup here http://www.myrl.com/ and here http://slurl.com/secondlife/Kiha/67/154/27
Cheers!
Sven Neumann
