I don’t think there are any high quality discussions left to be had with the current suite of redditors.
First of all, thanks for your comment, I appreciate the discussion.
To answer your point, I’m not so sure, there are more spectrums and gradations than clear-cut groups.
I’m probably against the grain here, but I still see some quality content on Reddit among the thrash.
And when I tell those people who post interesting content why they don’t come to Lemmy, they explain that they don’t have the time to post everything twice, and even if Reddit is bad, it’s still where most of the people are.
