Already did last year though it was gradual and I just stopped updating. It was easy for me to give up because I didn’t use it very much anyways. I couldn’t keep up engagement and with the fast pace, and I knew it. I wrote some promotional posts and tried to post regularly, but I still felt my morale slip and couldn’t regain it.
I also made a site on Neocities and post updates there. It took a lot of extra effort to code a site, but it was fun!
This year I joined Mastodon.art, and it’s an instance I can highly recommend for promoting art! It feels a lot more laid back and the larger character limit for posts is very helpful!
I’m not sure how quickly those invites will last for Pillowfort, but it looks like an interesting platform and I like its focus on building communities.
