Yeah, I generally do. However, the thing I look at more is join date. It's a simple thing, if you joined before me I consider you an older member and thus respect your opinion more than I would others. If you joined after me, but still post something interesting or useful then I also respect you. If you joined after me, have more posts than me (completely understandable) than I would look at the context of the person's post before I formed an opinion. I don't know if they changed it or not, but people used to run insanely high post counts because of the forum games, so that also factors into my perception of a poster. I remember a while back there was talk of those posts not counting towards your total, but I don't know if that ever went through.
Or there's always the people I remember, be it through an avatar, past pub club interactions, a funny username, or good posts that I remember. That happens a lot too.
The big thing though is if they can spell and formulate a proper sentence. I don't remember that being a problem before, but there were always a couple people (I think they've since been banned) that couldn't do either. I didn't care what they said, I just instantly assumed it wasn't worth my time.
