Really glad to read we're taking positive reinforcement into account. I read that gamifying aspects were being thought of as not-compatible with Wikipedia's seriousness and maybe that could be true but I'd say that in general the features of talk pages and homepage do look rather lighthearted in their essence so maybe a gamifying aspect wouldn't be be too far from what we currently have. Anyway, I wanted to share my excitement about the whole thing in general. Unfortunately, as far as I know, my homewiki (SqWiki) doesn't have those features enabled yet but I'm looking forward to them. (Trizek may remember I've been looking forward for such features for a while now.)
Keep up the good work! :)
