Another thing that occurs to me is these are not high traffic forums. There seems to be just a handful of posters doing almost all the posting in the forums I frequent here. There could be several reasons for this. One that pops into my mind is that the oldtimers have developed a sort of language all their own. They have history and get each others references and jokes. I get replies that make very little sense to me at times because I'm out of the loop. There may be so much of this that it drives many newbs off the site.
Also the use of snark may be a factor. There is good natured snark and malicious snark. Some may not know or have forgotten the difference. I become snarky not when someone is ignorant but rather when they seem arrogant, or self important and entitled. It can take a long time to figure out the lay of the land in a strange forum. Had I not had a lot of experience in other forums for several years I would have blown this place off a couple of weeks ago. I would have been one of those 3 post and gone guys.
I'd be curious to know how many lurkers there are here who wouldn't make a post if you paid them.
Like that one poster said, "if you want technical info eplaya is the place, if you want to discuss the issues go elsewhere"
