I’m especially curious to know if you made your own instances or communities. But if not, what other notable things have you done?
E: I guess I forgot to mention what I did, which was make a community and various posts. Considering making a full instance but I’ve never attempted something like that before.
Commenting, upvoting, boosting, and seeking out inactive magazines on topics I’m interested in, then making posts. My local magazine would be /m/stlouis so I’ve made a couple of posts there. No traction yet but I’ll keep at it.
