Some years ago I decided that, at some point in my life, I would try and involve myself with a gallery or museum. As with all things, it depends, but it seems to me that in such places you can find some of the most authentic and driven people out there. And it's probably quite fun to work with them.
I have found the most authentic folks are the low-key ones that have a booth at an arts festival or some other show.
I've been to galleries, and thought the vibe was really un-authentic. maybe I've been to the dysfunctional ones. Maybe that it is that galleries are more about something else than the art, more meta. (and they sold art not like this community gallery)
Don't know the reality of museums.
