Jose, I know you as a a dedicated man. But you know, that frame-by-frame animation is hard for most beginners and therefore, not popular for average man. Usually people use some sort of vector editors with inbetween technology and differens visual effects. Pencil for now is like a classic XX-century animation stand. It’s just for the enthusiasts. But animation made by hands, frame-by-frame looks more alive, and that’s why I love it and ready to work for the benefit of Pencil without any monetary. To connect the community for the general case we need some motivation. I don’t understand, how this social network can help. I suggest to make a contest of animation similar to what is on this website: http://showmetheanimation.com/do-it-in-ten/
I think that local developers will be more motivated if they will see that Pencil become more popular for more animators. Nobody want to work on the software which nobody use. That’s what I think.
