Thanks for the feedback. Interesting to see how Quora does answer permalinks. At the same time, then other answers, aren't easily discoverable.

Yea, upvotes only work, if the community "collectively" has a good judgement :- ) Also, I'm thinking about weighting upvotes, with how good a judgement the voter seems to have, based on trust levels and fraction upvoted and downvoted answers, hmm. So a staff user's or a trusted core member's upvotes, have a bit more weight, than votes from a new and unknown person.
