Not at all! I intend to continue posting my comics on my website free for everyone to see. Backers at a certain level will get to see them a little early, and maybe see some in-progress works and behind-the-scenes material, but I have no plans to put the comics behind a paywall or anything.
In fact, the idea behind Patreon is that if it brings in enough income, I’ll be able to turn down other less-fun jobs and focus more on my own work. That means even more comics for everyone to enjoy.
