yes

I have a hard time self promoting, but art communities help a lot.

Mostly to get involved with like minded people

It's really all of the above, as generally one leads to another. It's a great way to learn new techniques. For me I see something on dA that makes me go damn I'm not pushing myself enough and try to learn new ways of coloring/drawing/creating pieces. For instance I really didn't consider creating something totally in vector until I started following more of your work Shar. Thanks to all the tuts you've put out there it really piqued my interest in that artform.

Inspiration, get involved, and share my art

to see moar art!!!!!

All of the above.

ALL

Getting involved with a group of like minded people, mostly.

All of the above.

A lot of it is feedback, but then I get to looking around, and I get inspired, then I look around to get inspired.

There's really a lot to it.
