Definitely going to be some adjustments in the next update. The gain is too low and the decay is somewhat aggressive. We'll be moving in the balance a bit on either side.
I haven't seen any trolling or inappropriate use of the channel so far, which has been nice, but usage is low, as you'd expect. It only takes one person to ask a question before a handful of people jump in and start answering, which in turn makes more people comfortable asking questions there, but these spurts of activity are few and far between.
As far as the barriers to entry go, as we mentioned in the patch notes, we'll be flagging trustworthy community members with permissions to answer questions, regardless of Mentor Rating, in the future. Outside of that, we'd be hesitant to drop the barriers too much right out the gate.
Would rather this feature cultivates the right community over time, even if the growth is slow.
