For me the level of interesting content is just about spot on now, but obviously it depends on your interests.

I do have one suggestion though. Whenever you feel the urge to comment about how "hobby" communities are too dead, be more specific. Which hobbies? Which communities? Every time you mention one, the chances that someone who didn't even know it existed sees that comment and finds the community increase.

Look I'll start. I wish there were more crocheters around to liven up !crochet@lemmy.ca a bit.

Word of mouth is how niche communities grow.

(p.s. also spend some time blocking the news communities if you're not into that stuff, it makes a massive difference)
