This is like craigslist for artists.  You can buy, sell, exchange, collaborate, etc. through its interface.  I know it has been set up for over a year and there are still only 5 cities included.  I think there may have been a skipped step in the build out process to find out what cities would latch on well and how to expand from there because I would think the site needs more growth to be sustainable.  We’ll see!
