One thing I’m not clear about is the impact my home instance has on me. I joined lemmy.world and am currently using the connect for lemmy app. I know when I sort by Local it will only show me posts from lemmy.world, but beyond that are there any things to keep in mind?
I have read that lemmy.world has been hit by DDoS attacks but I’ve never had any problem using connect for Lemmy during those times as far as I know.
One thing that might not be obvious is that the All feed is different too, as it only shows posts from communities someone on the instance has subscribed to. But since there are ways to search communities across instances, it isn’t really a big deal. Unless you’re on an instance of one or two people maybe.
Federation and moderation are probably where the instance matters most. Also, the matter of who runs the instance is kind of important considering stability and longevity of the instance. (mine for example will probably be gone within a month once I break something)
