That's a big open ended questions. For me, it depends on which vehicles I have, as each one has its own Facebook groups and websites. And for the most part, Facebook groups have taken over internet forums, and almost made them obsolete. When I'm looking for a new group for information on specific vehicles, I look for Facebook groups first. If I don't like what I find on Facebook, or am waiting on approval, I will look for forums where I can start searching for information.Maybe there should be another thread started; I bet we've all settled on a few websites we like better than all the millions available out there. If you were going to help someone get started in one (or all) of your hobbies - which sites would you recommend?
There are also those who, even within the same specific items or hobby, will favor one website that the next person despises. Usually due to experiences with other members, or how the group is moderated.
