Block Savvy recently launched with a unique combination of differentiators (yes, the word for the day is differentiators!) in both their design and approach.

It’s designed around blocks, that can be focused on community interests or particular brands, and rooms chosen and altered by participants.  There’s a currency which one can earn by using the site and spend at the in-world storefronts with some kind of real world currency exchange possibilities.  Many of the in-world graphics are or will be based on digital photographs.

What also differentiates the site is that it has some level of backing from Damon Dash and that it was "created with brands, sponsorships and advertisers in mind".

All in all a very interesting experiment with a great deal of potential that appears to be based on a serious examination of social networks and virtual worlds to both capitalize on participant interests and on marketing needs.
