Originally started out on Beehaw due to the name. I like bees. I like cowboys. Win-win. Then they defederated from the two biggest instances, and I lost out on a lot of great communities.
Ended up switching to Reddthat since the name / URL was easy for my ADHD brain to remember and didn’t require typing a novel to join.
Anything revolving around collecting more obscure items. I was pretty invested in pens and mechanical pencils on Reddit…even though I don’t collect either. There was just something super satisfying about seeing all different types of pens / pencils and learning about them.
Also miss having a trumpet community! Hopefully one will eventually spring up and become active!
