At that time my answer had about 10 upvotes, yet I've received 170 reputation for it so far. Answers to community wiki questions aren't supposed to award reputation, are they?
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
The question became CW, but your answer hasn't. It's CW posts which don't earn rep. If for whatever reason your answer becomes CW, then at that point you won't receive any more rep from it.
I've wiki'd the lot; it didn't seem fair for only some of the (early) answers to be rep-gaining. You'll keep any rep you gained so far (even after a recalc), but any additional votes are for glory and badges only.
