Hi there ~~
I'm also on webtoon (The Glow) and I feel more comfortable there because there's way more people reading my series from there (around 1.5k on Webtoons and 140 on Tapastic) and more people reacting and comenting cause of that number of subscribers.
Despite that difference of subscribers, I'm still on Tapastic because those 140 are worth my time as long as they keep enjoying the story ^^
Also, you don't deserve a **** 2 or 4.5, I agree with you: webtoon rating system is something incredibly stupid that will always go against the creator, because there're a lot of careless users who rate without having in mind the effort and the time spent on each page.
