OurWorld

Ourworld is a neat mix of virtual worlds and gaming. You create an avatar, then earn "flow" or points to spend on clothing, rooms, etc. by playing games! I've only scratched the surface so far, but I love the concept. You can join for free, but can pay for a premimum membership. That gives you access to more games, features, etc.

I'd love to see a world like this for education, where you could have games on different subjects, earn certificates for subject areas, etc. By blending VW and gaming, you address the so-called weaknesses of both. So check it out and let us know what you think!
