I think it will probably happen at some point in the next few years.
As these korean tech giants begin to duke it out for surpremacy over the entertainment industry (even going so far as to to challenge hollywood.) having more content on your platform means more chances of finding those hidden gems that can be easily turned into franchises... And better yet the creators are gonna be small folk with little expectations, so that makes their job so much easier.
Due to it's creation process novels are much faster and economical than comics, a single writer can write enough content in a day that it would take an ilustrator an entire week or even a month to produce, so they are the easier medium to handle if you want to scout for hidden gems.
This is of course not entirely bad as you will likely be able to see more and more novels getting space in general entertainment, and better tools to make publishing easier and acessible, and that is always a plus.
As for wether i'd use... three things (other than TOS and legal concerns of course)
1Âş How easy it would be to post all my stuff over there.
Interface issues and all the what not, I got a boat load of stuff, and I would like to have it easily posted.
2Âş Content guidelines and if I would have to censor things.
Think this one is pretty self explanatory, I wouldn't want to censor my stuff... I mean... I'm not against it, but depending on how much I might not even bother.
3Âş Money
As much as this might seem cold, TAPAS doesn't actually pay me anything, and If I can start making some money for my effort, i'd surely do it.
