I think that Nintendo’s idea with Mii-verse is rather brilliant and improving (can’t wait for it to be on my 3ds). The idea that you can post a question on specific games or more generic topics and then have people interested in those topics reply quickly is awesome. Think about how you could implement this in gw2 with all the specific aspects of the game (dungeons, map completion, tips on so many other things, etc). It would make people have to leave the game less for answers and just be able to find the answers in an in-game feature that is similar to facebook and mii-verse.
