I'm glad that you're trying, that's something to be proud of!
I do think it's difficult to create an online persona and interact with people that you know in real life - but it's definitely important to frame the discussion in the right way. It's like, "Hey, I made this thing and I'm super proud of it. Would you be willing to support me by telling someone about it?" You'd be surprised by how many people are willing to help and also how much help they can provide.
Kwon Hyuk Chu, who created Green Smile and is currently doing this really awesome series called XINK3R joined Tapastic when we first launched. I remember asking him for a quick shout out, and he went above and beyond, going on a bunch of podcasts and being huge advocates for us.
I reached out to my old high school art teacher, and she showed her entire class (got a few them to start some comics too!).
The point being, putting yourself out there is really brave, and I think people are happy to reward bravery.
Keep up the good work!
