Supporter vs. Spectator

I just went and spent some time with Roget’s Thesaurus trying to figure out how I’d classify that distinction. Community vs. audience? Supporter vs. spectator? I’m still chewing on it. And the “support” I’m referencing isn’t always material! It’s just “people with a more pronounced interest in being close to the work,” and I’m trying to remember how to put them first in everything I do.

Is it gauche to quote your own writing from a different platform on your own blog? I don’t care! Heck the rules!! This is what I’m up to right now!!!
