/r/eurovision, although the season just ended so it would be a bit quiet right now anyway.
/r/fantasyfootball, that season is just about to kick off so would be good timing
If you'd asked this a day earlier I'd have said /r/casualUK but we now have [email protected]
And the various specific craft subs. Currently we're posting all craft projects to [email protected] but sooner rather than later I think it'll have to be split up into individual crafts because if there's one thing crafters love even more than the actual making stuff, it's showing off the stuff we made.
Oh yes, I'm on Mastodon too and there was a ton of Eurovision content in there (I even ran into someone from the tag in real life in the arena, what are the chances of that?!)
But it'd be nice to eventually have a community here too for those longer discussions, that's all 🙂
(plus interacting across the different services is still a little bit dodgy as evidenced by your tagging the OP of this thread, but I'm sure that'll get better over time)
