I run a ferret forum, and it is now just the few die hards still posting... There are loads of Ferret fans out there, but I think my forum is now the last true ferret forum still running.
There was about 4 or 5 other forums, but all the others did the parallel FB and forum thing for a while, where suddenly everyone moved over to FB, and the forum got quieter and quieter, till in the end they shut the forum down as it saved money, since FB costs nothing other than your soul. The other problem is Forum Spammers, I do not know how this forum does such a good job of keeping them off, but for me, I have to hand check 8 to 10 a day, to see if the odd real person actually tries to join up and that takes time, the more popular the forum, the more you get trying to join.
I do blame Facebook, as it panders to today's society, where they don't bother researching an issue, they just dive in and ask their questions, expecting everyone else to answer it for them, and as there is no historic data on there, it's the only thing they can do.
I have been researching Scroll Saws. and it's scary because all the info is 5 or 6 years old, as again, no one is posting to the relevant forums anymore, and any results that send you to a FB page have one answer and then 10 keyboard worriers questioning their spelling, grammar, or just plain contradicting the answer with out any constructive information.
It's a shame, but as a person who has been on the web since before it was even called the internet (when I worked at the University), I have seen it go from having not a lot of info, to turning into a great resource for finding the answers to most things, to now, where there is so much junk and advertising on it, that it's hard to actually find real opinions.
I think that the people on this forum are a minority that somehow having Nissan 4x4's in common seem to be nice people, and the ones that aren't like that, soon go away again. It's a bit like already said, this is more like a club/pub where we can talk about anything, and long may it continue.
