I pretty much don't. I used to post about things I was writing back when I was still active on twitter and had a decent amount of followers, but I decided I would not invest myself anymore in platforms that could arbitrarily decide to ban me (which is exactly what happened multiple times). my strategy however has always been to imbue my writing with a certain amount of memetic potential that will get people to talk about it and share it, which is really just how I'm already inclined to write anyways since at heart I'm still just a shitposter on the internet
