@youronlyone I've been doing serial fiction online for over a decade. Mostly on my blogs, though I've tried Wattpad (weak engagement) and RoyalRoadL (somewhat better, may return) in the past.
I have both serialized works that I publish bit-by-bit and seat of the pants writing, a new 2k words every couple weeks. That last is literally based on reader votes, as I have no set ending. Rarely get even 5 votes though, so maybe not what you're thinking.
