Then why the grand statement?
If your interested enough in a subject to be a active participant for 6 years and 11,000 posts then that interest doesn't just stop.
So it's a pretty safe bet that your going to want to come here again to read a post or search for a article you remembered.
Chances are that even if your not interested in the subject right now, sometime in the future your interest might ***** again.
So the grand statement in cases like this just screams to me ASW who cares more about trying to make a statement than loosing interest.
Don't get me wrong, there are a couple of folks on here that sometimes drive me crazy, but they also offer good opinions sometimes with well backed experience, so stomping off in a huff declaring "i'll NEVER ever ever ever come back" often comes off as just a bit desperate and attention seeking to me.
Bit like a kid that refuses to eat their lunch because they didn't get the gift they wanted.
Not saying that's the case here, as i don't know the op or the situation and have no real interest enough to search to see there has been a argument.
In general though these type of farewell threads just seem a bit attention seeking to me.
