I visit FlyerTalk for the travel information. I have little interest in the Omni forum. As long as it is part of FlyerTalk the posts there should count.
Does post count really matter?
I gave up on caring about post count back when I reached 500 or one of those critical numbers and I got my new "super duper poster elite" title. A couple of days after I received my upgraded post count name, FlyerTalk changed the system and I lost my special post count name.
