I was looking at the permissions available to me, and was wondering why upvoting an answer is unlocked before commenting on any thread. I understand that it's, in part, to reduce commenters who spam the site. But it's kind of a hindrance to those of us who want to help answer a question, but need more info.
Currently, I can only answer a question, not comment on it, and as such, I have to wait for someone with enough rep to ask the question I was going to, thus slowing the answering process, unless I decide to throw the rules out of the window and just post a comment in the answer area. If I do that, I'm reducing my contribution to the site, and increasing the anarchy.
