{I think it's kinda strange myself. Why would they actively attempt to recruit artists from another site that way?} They've been encouraging people to post stuff both to their store and any other stores out there since they finally got the store running. They don't want anyone selling stuff exclusively through them, nor do they want anyone selling stuff exclusively somewhere else, it seems... A kind of "Share the wealth and keep the COMMUNITY alive" mentality (in other words, they're idealists... For once I hope the idealists are right...).
