@TheGodEmperor As frustrating as it can be, the reason for that is that the industry has gone through massive shakeup. As you probably already know, manga was traditionally released in weekly magazines with around 18-page chapters of a bunch of different manga. Production of these chapters relied not just on the artist doing the pencilwork (or in some cases like Yu Watase, the writing as well) but an entire team to do all the inking, erasing/cleanup, screentone, the gofer to take the manuscript down to the print shop, etc.. But now, with software like Clip Studio Paint, the work of a team of 10+ can now be done by a single artist doing all the work (save the writing, generally). And since this saves publishers like Kodansha a HUGE amount of money in both employees and resources (Deleter charges a /fortune/ for screentones alone) they've been especially encouraging of young indie artists with new series. But since it's only one single person, they've had to considerably relax their deadlines and page commitments. (You can even watch a lot of these artists working from their Pixiv streams first-hand, like the artist doing Seijo no Maryoku wa Bannou Desu.)
In short, the new thing now are short mini-chapters being released online due to the drastic cut in staff. On the one hand, it sucks that chapters are so short, but on the other, it's a VAST improvement for the working conditions and opportunities for Japanese artists who had some pretty appalling working conditions previously. It also means we'll be seeing a LOT more different series in the future and from many more artists. (Some of which would have never seen the light of day under the traditional system)
