Something like Misskey or its forks like Sharkey (not a shameless self plug no) which offers more fun features and customizations
That would be fun! But it’s also a bit of a challenge to strike the right balance between features or platforms that I can fold into omg.lol overall, and the time and attention requirements for managing and maintaining those features or platforms. It would be easy enough to spin up another server and install Misskey on it, but that also comes with a permanent responsibility for moderation and maintenance. So hopefully you can understand why I have to be a little selective in what I can offer here.
