I’ve been browsing Mastodon daily now. I’m finding the experience reminiscent of my first few months on Twitter, where it is was a challenging to cultivate a list of people to follow in the very beginning. I think federation adds an additional hurdle, but it is still coming together slowly but surely.
I use Stable Diffusion to make character portraits and scenes for my D&D game that I run in Foundry. Better than trying to scrounge Google images!
