Honestly, it's so easy to get hung up on the pie charts and popularity contests -- when all of that energy could go to harnessing your craft. That, and trends come and go. For a good while, horror was on the top charts. Then it was the Gamer tag, and so on.
Hell, even Twilight ran its course. Ya'll know about the vampire craze I'm talking about.
And if people are complaining about BL, I wanna know where they were when people were making Zombie movies, comics and films every other month because of things like The Walking Dead and World War Z
Most things just come and go, though some things last longer than others. I just go with the flow, and I feel more people ought to start doing the same.
I get it -- it can be annoying, and it might feel like you're not getting the audience you'd want. Doesn't mean those artists doing the popular thing didn't deserve their audience, and it doesn't mean the work you do is lesser.
If you choose to not do something because it's not popular, that only lessens its chance of being popular in the future.
That, and Tapas/Webtoons are not the sole provider of comics. There are millions of other comics out there are not BL or romance.
One of the main reason a lot of creators here think it's heavily popular is because they refer to these sites as the sole provider of online comics, and they're probably not used to actually seeing an actual surge of popular content.
