Bikeforums as a guest, gj sporadically and a potpourri type forum, has a little of everything.
I tried a few other bike forums but most play to the elite cyclists, which I am not one of.
I have found that a lot of forums are like that, it will be hard to fit in if you're not into the latest and greatest or what the " coll kids " are into.
I have also noticed on some forums there will be a bit of an it crowd type , some of them are savage beasts.
I know on bladeforums there one such pack and if they decide they dont like someone that person is toast.
They'll set their sights on you, they'll find something wrong with everything you post, and they'll take years old comments out of context, and because they create their own definitive idea of who you are they'll see what they choose to you in everything you post.
They're good at either running people off or pushing them into getting themselves banned, because they know how appear in the right with everything they stay out of trouble and don't get outed as trolls.
