Why not be democratic about this and hold a poll on the subject?
So here it is.
I'm not being particularly democratic here (Call me El Presidente), the poll is more to get the general feeling - we'll continue to make decisions on little details like this behind the scenes really, and plebiscites on everything would be a bit of a nightmare.
My own view; is that it doesn't really matter what the post count is. People get to know who's who, and maybe each individual post gets judged (if that's the word) on it's own merits.
But it can provide an indication for new bods of who's been kicking around for a while - so it isn't really a broken thing, purely a detail.
The barracks not counting will stay - seemed fair enough that if the postcount is indeed any sort of worthwhile indicator at all then it probably shouldn't include rattling on about Sport, Musak, and what random event may have pissed one off that week .
In that vein - any other areas that maybe shouldn't count?
Saying again, this ain't a poll with a definite set result at the end - more a bit of curiosity - I'll leave it open for 60 days (though I can extend that if it gets entertaining - multiple answers are allowed, so you can lean one way, but also not really care if you fancy).
