I see your point. Though I'm sort of...comment whore? XD so it doesn't apply here the criteria. Also, check my tags number (and while you're at it, my palletes :P)
Option #1 sounds like bandwidth and time saving, which is what I'm after. I comment as I go along listening, but voting for me usually it's a long process of editing and reediting tunes' votes over and over until I'm at least 89% happy with the results, so actual voting occurs long after I made comments and on my end. Comments are on going on botb's end, and so are votes but on my end, but when I put votes no botb, they're final and for good.
oh! off topic :D
