I find an amazing amount of modeling on FB.   I'm "friends" with Kow Yokohama- how cool is that?      Facebook is how all my non-modeling friends see my nerdly achievements- old pals, comics artists compatriots, cg industry peeps- as well as modelers from around the world who don't frequent English-speaking forums.    That said, I still post my work in good old fashioned model forums for the close contact with my styrene peers- they are still the best place to learn in interact with like-minded hobbyists, and get the best info on new products, kits specs and reviews, etc.
