Beam has a real clean UI with lots of potential. I think a mobile app will take it to another level, because i believe that maximum engagement depends on phone notification, whether it's push notification or a little red bubble, that appears on the app logo, to let you know that something new is going on in the community.

I love the gamification. it's not perfect yet, i have lots of ideas to improve it, but what they have so far is solid. It can only get better. Pretty good support so far. My chat messages and emails are answered by friendly people within a day. Their road map is loaded with cool features and updates. can't wait for those features! i'm excited.
