I commented to someone OTHER than the OP, because I know him and not the OP, because I agreed and that was an easy way to assert what I wanted to say.

That's a cardinal sin? I had no idea -- I always kinda like it when I see people replying to other folks instead of directly to me, when I'm the OP. I mean, if they reply to me, that's fine, but I always feel like I must be doing something right if people feel like it's okay to reply to each other, instead of all having one-on-one conversations with only me.
