I had more interesting coversations in 2 weeks here than in 10 years on Reddit, so can't say I agree.

I don't think so. As I see it in the Lemmyverse there are threads without comments (image posts for example) but if there's a topic with a question or where opinions can made you can find activity there.

Yeah, it's not a million subscriber reddit community level activity, but it's still activity.
