Yea truth be told I still visit r/soccer and r/reddevils to catch up on football related news every morning/evening. The communities on Lemmy are still growing and while the more popular communities are very active, niche communities like sports will take some time.
Check out the football community on Lemmy, it's starting to get active. I've recently started posting too.
I'm not sure how to link directly to a community, so here's a link to one of my posts. You can click on the community and subscribe https://sh.itjust.works/post/701657
