My guess is that kramer's issue with you is that you have a tendency to comment on everything, without really thinking about whether your post is appropriate.
You haven't posted anything rude (like Nate used to do) but you can sometimes be... I dunoo, it's like you lack an edit function. Like you're trying so hard to be liked, without realising that you're being a bit overeager. Sometimes... silence is golden.
I'm trying to say this nicely, because you seem like a genuinely nice guy, and you seem to like my comics (well, that should have no bearing on this, but, hey).
I guess an example would be when you posted who you thought the winners would be in the next round of the Comic Cup. It's one of those things that, it's hard to describe, but you just don't say in the open forum. I've had private AOL discussions with people about how it could turn out, but somehow posting my thoughts seems wrong, possibly because it would make the people I'd predict as being beaten feel bad.
There are exceptions... I predicted that kaufman would beat xpac mainly because xpac had proven himself to be a completely annoying doof by that time. I didn't fear insulting someone I thought was pretty much an ass, anyway. :-)
