If one wants BITOG to simply be a database/ knowledge center- it will be a ghost town.
There is positively validity to that point, i know several - one pistol forum and one truck forum (actually probably more than one) that has suffered. Both of those forums have a tremendous amount of reference material but the posters for the most part are gone... Facebook groups almost killed forums completely.
However there must be a balance, i think BITOG does a reasonable job of striking a balance - one of the better that comes to mind...
I know one forum where you state something as a fact and can't support it you will get a vacation, you say "sucks" or "screw" or the proper name of a file with unmarried parents and you'll get a long vacation at best. That might be a little draconian but it does keep it very technical and accurate last time i logged in it was very slow. I know another one where pretty much anything goes except saying something derogatory about a members family or outright pornography. That might be a little lax, though in the technical areas of the forum things are still pretty accurate, and members are very helpful, in fact it is the the place where if you say you need help, someone will promptly drive 200 miles to help you or organize a cross country relay to get you what you need. It is extremely active.
So i guess what i'm saying is a lot of it is the culture that is promulgated in the community.
