Like adding a badge store to spend credits or one enough badges unlock more features. Like special signatures, gifs, display photos or flares? Or a online CAS where you can create your own mini sims (maybe the My Sims design) on here and unlock clothing. Like sites like gaia or tinier.me did. Or special stickers, but it seems like they having been sticking to the same like/insightful/awesome system.

But without a reward system or anything in place like that why are badges in effect at all? I get notifs for them but i usually ignore them since they don't change anything.
