I host my own instance, but I like selfhosting as a hobby. I really love having all my account/login stuff on my own hardware and my own backups. If I break something, its just my own stuff that broken, no harm done to any other users. I don’t really plan on hosting any of my own communities, just participating in others. I’m an avid seflhoster, and my setup is pretty exotic compared to the vast majority of hosters, but I got the whole thing working perfectly over a day. Much better than when I tried to get mastodon working. More power to more fediverse stuff though.
