Just putting a little advice out there: Right now it's really difficult to find your patreon. I'd have to google it to find it as a tapastic reader. Put it as the link in your series' editor (where you can add a link to elsewhere that you update your comic), make your custom ad banner actually link to the patreon (last time I checked it links to your tapas series). You could also link it once in a while in your author's comments with a short note of your main "selling point". Basically the most appealing reward you can give them for their support. If you've got early access on your patreon, that's probably your selling point.
I haven't checked you out on webtoons, but I would advice you to take similar measures there. Link your patreon up to your webtoons account, and your readers will see a small "support this creator on patreon" notice with a link to it at the end of each episode. If you add a very small banner to your updates (goes both for tapas and webtoons) where you mention that little selling point you've got, and just casually link it in the author's notes, that will actually be more effective and appear less naggy than if you constantly mention it in author's comments is what I've noticed. But that's just a little tip, you decide for yourself which you prefer more, if any.
I am unsure of how Webtoons as a company would be able to affect the way individual users of the app behave? But Tapas is definitely becoming a good competitor.
It is possible to communicate with readers on webtoons but due to the way the site is built it is much more difficult to carry a conversation or notice if anyone replied. Thus they are also less likely to reply overall. So in that aspect, I do very much prefer audience communication on tapas.
Tapas audience also appears to still be more closely attached to the creators and more likely to agree with their personal choices. That being said, this is something I've definitely seen improvements in on webtoons lately.
I think it could be because the Discover tab is being filled up faster every day with more and more good quality content, to the point where webtoon readers are now more familiar with seeing independent, non-contract creators with more varying update rates and methods. Being exposed to more of this, they begin to see creators more like humans than just as vessels of comic creation. It's no wonder they didn't view it this way before since the contracted creators are rather distant.
