Not a fan of the Senators and don’t follow hockey much, however came across this in my feed since I sort by New and Local by default.

The community looks kinda dead. Lemmy has a disadvantage to Reddit in that the userbase is a lot smaller, so more specific communities such as specific NHL teams need a little more heavy lifting to get them off the ground. It’s a self-perpetuating problem unfortunately. People don’t engage with the community because there’s no activity, but there’s no activity because people don’t engage with the community.

You could post news about the Senators every now and again to show people there are others on Lemmy who are just as interested in the Senators as you are. Heck, depending on if you’re up to it, you might even be able to ask the other mods or an instance admin to be a mod of the community after a bit of posting activity. Just on first glance it looks like the community could attract more users if the sidebar was beefed up a tad.
