Tapas recommends 500 to 1500 so I try to stay within that range.
Yes, that means I have to split chapters and they don't always have a neat spot to cut off on. My scenes usually run for at least 1500 words. For some of them, I had to write an intro/outro sentence so it would make sense. In other cases, I was like screw it, you want it short, here's short. Figure it out. Essenitally, if someone is binging, it doesn't matter anyway.
I'm toying with an idea of writing a webnovel - one specifically designed for this format - each episode is a fully fledged story like in a sitcom. It's going to be a challenge to write a book in a series of flashfictions, but on the other hand, I do like writing flashfiction so this could be pretty cool.
