I would definitely be interested in such a recs community! I have never modded a comm before, so I would want a co-mod if I made one, but I might do some kind of interest check to see if other people would be into the idea.

I would also have to think about the community purposes of reccing vs preserving. I think in a multifandom space, reccing makes more sense and preservation might be too ambitious, but I would love to see some other single-fandom communities with an archival intention out there too.
