I think the Escapist forum culture as a whole is very heavily in favour of quality posting over post count.
Some like Iron Striking From Shadow, Contemporary Ancient, Johnn Johnston (sorry couldn't think of name that's like the Great Ten from DC) and Savage Butcher-Honoured jailer Gaoler, have been here briefer than others but have proved themselves to be bigger contributors than some others with more time under their belts.
I think more of what influences me is what people say, how they say it and if they ignore those unwritten laws buried threads covering acceptable presentation.
Text-walling for example I see as a sign that whoever posted it, is not a veteran of these boards. Sure they may be arguing coherently and have a high post count, but I see many of us here will tell them to present their intelligent arguments in an intelligent fashion, but in a more to the point manner.
Its the same again with forgetting to use a "." or a "," in a paragraph, making it just one sentence meant to be read by a reader with an extra 5 or 6 lungs.
I do give some respect to members who bear Sign of the Epic Fishburne or Sign of the One Staring Into The Middle Distance As A Way To Pass Off Air-Headedness For Enlightenment. By not getting banned for so many posts it's a good indicator, to some degree, that they're not Sir Spamalot the Failure
