The one that really irks me now is that Nautilus in Ubuntu doesn’t show thumbnails for PNG images in the file selection dialog. It’s such an ass-backwards change that I’m legitimately shocked.
Honestly, I think the #1 problem to be concerned about right now is that there a lot of people self-hosting for the very first time, that maybe don’t really have much experience with hosting or moderation. It’s tough! There can be a lot of drama, random software failures, lost data, and disappointments that can happen. An instance can go under at random, at any time.
It sounds bad. In practice, the day-to-day can be fairly smooth sailing. A lot of people just kind of need the experience, need to make sure they’re not the one person moderating thousands of people on a serer. Making sure that moderation is a community effort, that the server has backups, and that there are channels for donations to support the instance - those things go a long way towards long-term stability.
Okay. I’m glad that the situation is looking better, and it’s probably more on the Ubuntu people than the Gnome people, but it’s still an incredibly shitty experience.
