Tapas has more of a set that allows creators to organize things better and interact with their readers.
Compared to Webtoons, Tapas has creator walls for talking, leaving announcements, etc. On Webtoons, both readers and creators don't really have a page? Like, you're just a name basically (unless you have a comic or two). You can't really click on someone's name. You'd have to look them up, and it might be hard if they don't have a comic or something.
Tapas also now gives readers ad creators a chance to send messages to each other (kinda like Ko-fi). So now people can do "Thank you for watching" without having to send it to everyone individually.
