In general, yes, knowing a little about a creator will change how I view their work, but I have yet to meet an artist who has turned me completely off their stories just by being themselves. Granted I don't know any fellow artists very well and perhaps if I had a bad experience with one I would hold a grudge, but over all knowing more about creators makes me want to help them more and show them some appreciation. It gives me a better idea of who is sitting on the other end of the line waiting for feedback.
I'm quite active on this forum, as are many creators on this site, but first and foremost I see you people here as peers, not audience members who need protecting from the real me. I wouldn't post half of the things I write here on Twitter or Facebook or Tapastic' main area because it wouldn't be appropriate, and though I understand that readers from the main site can access these thoughts just as easily as any of you I'm willing to take whatever risks come along with that for the sake of having a group of people that I can help with their work (and whose work I thoroughly enjoy) and who will also support me in turn.
Maybe it's just me but these forums don't seem to have garnered much interest from the pure 'readers' of the site. It feels more like a creator's corner and it's a wonderful thing to be a part of. I don't have anyone else to talk to about this stuff- no one in my life does this, most don't even know that I do- so where would I find comfort and support if I didn't reach out to you?
If one of my readers feels alienated or disturbed because I'm Kate and I live near Manchester and play games and shoot shit in the Crossed Keys pub when my friends are in town then that's too bad. I don't want to offend anyone but then I don't want to have to police myself in order to protect people who don't even know me. Whatever happened to 'be yourself, don't worry about what other's think'?
Then, on the other side, there are artists and creators on Twitter who air their dirty laundry online all the time with no regard whatsoever for who will see it- readers, family, employers, colleagues, whoever- and there's celebrities, actors, business people and YouTube bloggers who regurgitate whatever they feel on everyone anywhere. Why? Who knows. And yeah, it makes me cringe sometimes, but not everyone does it and what's more it doesn't seem to change a thing.
TLDR; Where you draw the line is up to you. I try not to judge anyone too harshly for the things I read and see on here unless someone's being downright shitty in which case they can reap what they sow.
