"Spending more time on UI = spending less on quality."
I disagree.
The inability to reverse incorrect votes reduces the quality of the site by assigning incorrect scores to comments. In fact, many comments are apologies for accidental down-votes.
Also, not being able to comment inline means thread context is lost when comments are being composed. It is very likely this results in lower quality comments, which reduces the quality of the site.
A good UI can and does lead to a higher quality sites. Keep things as simple as possible, but not so simple that quality suffers.

Just my opinion.
