We’ve already got a few UK-centric communities popping up, which is nice, but I think one that would be good to have on “the UK instance” would be AskUK. As a bonus, you could pin a question at the top, something along the lines of “What other UK communities are available on Lemmy” and link to all the other stuff like !ukcasual@lemmy.world , !chilluk@lemmy.ml , !unitedkingdom@lemmy.ml and whatever other ones already exist elsewhere.
