I don’t have 500 subs, but I can throw my stats out there in case it helps at all:
I’ve been here since Halloween
with my novel and I have 76 subscribers now. I’ve got around 65 chapters (I probably made the mistake of posting too much too soon, since I was new to Tapas. I now try to post weekly).
I posted one of my comics on December 13th and have 103 subs. Though, I’m rather slow at updating my comic since I’m new to webcomics/my IPad (it only has four chapters so far).
I’ve got 112 on my other comic posted at the end of November, but I haven’t had time to update this one much. I’m also waiting for my art to develop to dive back in since it’s a story that means a lot to me! (Three chapters and a prologue teaser).
