"new" == ~3 years old (but looking to move from alpha to beta in 2024 IIRC). It's a good server!
I think forcing all posts to be opted-in to the search, and depending on users to opt-out, would be far more controversial? Either way, the user does get to control this within the platform.

I do not know if it is on the Fedora roadmap, but I can recommend taking a listen to the most recent episode of Linux Matters, where the three hosts talked a lot about backup strategies, and also mentioned GUIs.
I've been enjoying the first couple of episodes of Strange Planet on Apple TV. I wasn't sure they could translate a comic strip into something that runs 20(ish) minutes, but it has had me laughing a lot.
Oh, and listening to Messy, the new album from Cindy Alexander. She did a super intimate (audience of 3, me being one of them) livecast the other night, it was really nice.
Also: they remastered the Lush albums? I'll have to check that out.
Reminds me a little of the Rook design. CoreXY right? Tell us more about it!
I wrote about this on my blog. I like the notion and points made here, but I also think we're not helping by re-inventing things that already exist, so I'm torn on it. I have been happy with the existing one.
