I feel that art is art and should not be rushed or forced to adhere to strict scheduling. I mean, I certainly appreciate when it does (I like knowing that a new episode of a comic or novel will be posted Monday at 11:00 local time), but it's not the end of the world. That said, if an artist or writer is going to drop a series they should do certain things to ease the pain:
If it is a long series and has plenty of followers and it's dropped, do your readers a favour and post a summary of how the series would have ended if you hadn't dropped it. I recently spent several days binge-reading a webnovel only to find it dropped on episode 175. Thankfully the writer did exactly what I said above and posted a full summary of what would have happened had the story continued. Even though they dropped the story (for personal reasons, which was also explained and made it understandable) the readers got closure - characters we followed through 175 episodes of story were not simply abandoned.
If a series is to be put on hiatus, make a post that it is going on hiatus. Even if you don't want to tell your readers why, at least tell them that you're doing it. Several series that I follow simply stopped updating. Some of them have been more than a year now. No explanations, no "we'll be back, life got in the way" messages. Just stopped in the middle of the story. That is very disrespectful to your readers.
If a series is going to be dropped and never picked up on again, the best thing to do is to delete it from Tapas. That way you don't get people discovering the story and starting to read it only to come to a dead end. If it's not deleted, at the very least the first episode should be edited to clearly let the readers know that the series is incomplete, abandoned, and will not be finished.
As for myself, I cannot bring myself to start writing a new story before the current one is finished. This actually takes a lot of determination from me, because I have ADHD and have the attention span of a golden retriever on meth. Even as I'm writing one story I have another in the chamber, but I know that I must finish the current one before starting a new one or it'll never get finished. And I also can't bring myself to start publishing a story until it is completely written. Once it is written I can start publishing on a serialized basis, knowing that I won't leave readers hanging - even if I lose interest in continuing weekly updates I can upload it all and let the readers decide whether they want to finish reading it or not.
I say "losing interest" not in reference to the story itself, but in the art associated with it. My stories are "illustrated webnovels". Even though they are fully written I must still make up a new image for each episode, and those take time and effort. I've never lost interest yet, but if I do I can upload the whole thing without images and it'll still be a normal webnovel.
