I don't know if this has been noted yet, but I noticed that the "Discover" section on Webtoon allows for somewhere between 130-160 pages per genre, plus a ton of pages (600+) for the combined Discover section!
I think that a change like that for the "Fresh" section could help give smaller creators a higher chance of being discovered. With only 5 pages and so many creators, an updated comic enters and leaves the "Fresh" section super quickly, while on Webtoon, it takes much longer to get bumped, which gives creators a longer exposure to people browsing through active comics. It's also easier to switch between categories, since they are horizontal links and not a dropdown menu.
A higher visibility for the "Fresh" link would help as well (Webtoons "Discover" is at the top of the site!). I know Tapas needs to promote their premium comics, but the link is buried all the way at the bottom of the page, which could lead people to believe that the things promoted on the top of the page are the only things offered on the site. Plus, more users reading non-premium series doesn't = a loss for Tapas, since those readers may be more inclined to purchase coins to support their favorite small creators, and are spending more time on Tapas in general if they have more series to read.
