I generally wait til the end of the voting period to reply to comments on my own battles, partly because I don't want to rack up unnecessary/false comment counts, and partly because like Will is trying to express, I don't want to come off as being defensively responding to every bit of critique.
It's a policy of my own to thank everyone who's left feedback, so I feel that doing that after every comment given also creates clutter. That said, sometimes I worry that I sound dismissive in my "Thank you everyone for all the feedback you've given me" blanket response, AND I want to switch it up a bit so that I don't end up repeating the same phrase over and over on all of my battles.
It really is nice to see even short "Hi I saw this it was cool" comments, because I'm a nerd and like to see who's had a look at our battle.
As for commenting on other peoples' comics, like I inarticulately said in one of the Voidcast episodes, even if it's not a magnificent essay, I try to just go and write up a little bit of feedback. What was good about it, and what could use a bit more work. I know I'm guilty of leaving a couple "You guys did pretty awesome I like your comics" messages so please don't get mad at me I'm trying ;'D
Feel bad for commenting, feel bad for not commenting, feel bad for not saying thanks, feel bad for saying thanks, feel bad for ERRYTHANG
