It really depends on the poster, and what he's/she's done.
It's pretty well seen in the Silent Hunter mods forums, some people just start shooting mods out as soon as they join up here (Silverwolf in the SH4 mods forum comes to mind foremost) SW is still below 500 posts IIRC.
I'm on here for a decent chunk of my day. I love this community and I like to follow a lot of stuff that goes on. And, being a modder, I have to follow my mods and try to help people with their various bugs they might encounter in my mods. By no means does post count have anything to do with respect. If anything, other people will listen to what you have to say.
But generally a good poster is one who doesn't get offensive with other forum members, doesn't spam (the advertising kind, else Jimbuna would be long gone,) and generally acts like a good person, who doesn't force their opinion on others.

at least, that's my opinion...
I'm sure some other people might answer your question differently.
That's why this forum's great!
