That depends a lot actually, I think? I really like DeviantArt layout, but it might be because I'm using it for years now, haha.
It's a problem that could be easily fixed if they wanted to though, they can make a "New Comics" page or a "active comics" page too. Honestly fixing that one is not hard, it just requires that they actually want to do it.
Of course, some people could try to abuse it, but then it's their job to fix it as well x'D
I dunno, I am logged with Google+ maybe that's how?
I probably should try instagram after all. Huh.
Okay so... The webtoons thing, since we work in a team, I kinda don't understand the need of scheduling, since I receive pages on Saturday and finish them for posting on monday already.
Also, DA is kinda of... You NEED to spread your art to attract attention and make yourself noticeable. Groups, forums, and all that jazz.
The contrary happens to my and my mate's comic. We are underrated here on Tapas, while on Webtoons we flatuate between 9K subs and 12K subs with around 300 comments per update. So it really depends on what your story is focused on.
I noticed that BL's do well here on Tapas though.
