My last year of Reddit (prior to the API purge) was very much filled with low effort comments. You get a lot of votes and comments but the votes don’t matter and the comments are largely empty one-liners. I doubt it’s gotten better since I left.

I’d say even the assholes on Lemmy put more effort into the comments than Redditors do. Except tankies who just love to flood the comments with their copy paste list of sources for “everything”.
