Of course it's worse. It's lacking my stellar contributions!

More seriously, I think it's probably more of a perception issue, though I do think some small but real percentage of engaged redditors are gone. I still pop by to check a couple of niche communities that aren't doing much here, and to hunt for a daily link to share on /m/cfb as the specific sport mags/communities don't seem to be as active, especially for the ones in the offseason. I don't want to treat it as some sort of purity test, but for now at least I'm trying to put my energy into contributing to the discussions on the Fediverse and just sort of passively consuming from Reddit, without commenting, when I don't see what I want here.

My link aggregator history goes from Fark to Digg to Reddit to Kbin. TBH I think this one will be slower and less complete of a transition. I don't think Reddit will zombify like those two sites, but I do think that over time, enough people will leave for lemmy and kbin to make them vibrant spaces for a lot of communities, especially if Reddit starts chipping away at the ability to self-curate and thereby self-isolate from the biggest general interest communities that are more noise than conversation.
