Clarity helps. Three confusing parts to your post:
[CUT] ... those who don't have much to say... [CUT] ... applied to all posters ... [CUT] ... could lose me
If they don't have much to say, fine; if nothing to say, not fine.
If they're "posters," they've posted something and this isn't applicable.
If you really understood the issue, it wouldn't be applicable to you.
Sorry if this isn't clear. It's very basic maintenance to have more-legitimate member counts.
