How do you choose an instance and does that have a significant effect on your Lemmy experience?
I originally chose to make my account on lemmy.world since all the content seemed to come from there. But I've since learned that I can fill my feed with stuff from any instance so it feels like it doesn't actually matter if I'm on lemmy.world or not. At the same time, Lemmy.world seems to be frequently under attack so I'm wondering if I should change instance but have no idea what I should even be looking for when choosing.
I personally opted for kbin.social - I like the UI more, I like the community in the kbin-specific threads, and I like that I have the option to follow Mastodon users and interact with the whole micro-blogging side of the fediverse as well as using the "threadiverse" (Lemmy, etc). I think the occasional issues are bound to happen regardless of your instance, purely because it's such a new and growing platform. kbin's largely been rather stable, though.
The biggest downside for a lot of people is that kbin isn't supported by most of the mobile apps yet. Personally, I don't mind this - there's a PWA (progressive web app - essentially just a fancy bookmark to the mobile site that keeps it in its own unique browser instance with the tabs, menus, etc, hidden so it looks like an app) that works really nicely. The mobile site is really nice to use in general, so I've no issues just using this until a killer app comes along.
Similar thought process for me. The only downside I've experienced thus far is that once or twice a week, I'll get error messages when I try to interact w/ content (upvote/boost/etc).
I think I'll likely create another account when Threads joins the federation but kbin.social chooses to defederate 🤔
