This is me. I still go there for two or three subs that don't have critical mass here (thus no conversation). The upcoming weighted sort algo should help a little, drawing people to smaller community content.
But I also moderate a reasonably large sub there, and have stopped attempting to grow anything there -- just spam removal, manually.
But I don't post new content there. Sometimes I'll reply on a comment chain. Here I post new content and interact a lot more.
I'm using Lemmy Connect as my app (like 98% of it). What's interesting is, when I use Reddit I refuse to use their app, so I'm using old Reddit, in a browser. But I catch myself attempting to swipe on comments using the Lemmy Connect gestures.
I quit Reddit 2 years ago due to the content becoming more and more toxic (maybe it was always toxic) and I'm just so dang happy that my favorite 3rd party Reddit apps have a Lemmy client. I'm using Sync and it's like coming home. Functionally identical experience but with a cooler community.
I didn't notice much degradation after the 2016 election enshittening. I set to work blocking all the power users and was able to to maintain the post-2016 level of quality right up until I largely quit.
There are two subs I use that have no Lemmy equivalent (one of them probably never will) but otherwise Reddit is just a marginally better StackOverflow for me now.
Also I must admit the Excel subreddit is simply too useful to quit. I'm a damn wizard at this point and these people still surprise me.
