I noticed that lemmy.world and slrpnk.net host old.lemmy.world and old.slrpnk.net and I was wondering if there was any interest in doing that here. Personally, I think it meshes with the SDF vibe.
Edit: this would be in addition to regular Lemmy
Edit 2: it looks like they added it at old.lemmy.sdf.org. Thank you @SDF@lemmy.sdf.org!
I think having a noscript site like old.lemmy.sdf.org available could only be a net positive, I can't imagine that it would hurt to have it as an option, as long as it's not too much work to keep it running.
