I have no idea what all this would entail, because I'm not a programmer by any means, but I don't see why it wouldn't be possible to build a virtual marketplace for users to visit!
This would definitely allow for more personal interactions between users; as well as allowing some of the more inexperienced users to introduce themselves to other users or communities!
Plus that, you could start having in-game competitions or something along those lines, which would definitely boost user activity on both @cryptocompany and whichever community holds the competition!
