[Edit: Issues, Bugs, and Requested Features should be tracked at Google Code, not here -- matt, 2010-04-23]
Less Wrong is still under construction. Please post any bugs or issues with Less Wrong to this thread. Try to keep each comment thread a clean discussion of each bug or issue.
Requested features... sure, go ahead, but bear in mind we may not be able to implement for a while.
But there is a clear bias towards not voting if the comment is neutral, as opposed to when it's really good or obviously bad. The cost of wasting anyone's time is subtle and not obvious in any single comment, hurting only in volume. We shouldn't create any incentive for additional waste of breath to fill the comment stream.
