When mindlessly browsing Reddit, I found that I usually just jump directly to the comments, read a couple, and continue. Lemmy seems a bit more curated (read: smaller), and therefore it’s easier to actually engage in discussions, which leads me to read the article, think critically about it, and respond (if I have something to say) in the comments–bigger is not always better!
I think a reason for this is that there’s far more botspam than anyone guessed on Reddit. I have no idea exactly how inflated their user numbers are, but the fact that traffic only went down by ~10% during the blackout is quite a big red flag.
