I am theoretically switching over from Reddit to Lemmy. Finding myself spending more time on Lemmy than on Reddit. Maybe it’s because I am limited to using the desktop and can’t aimlessly browse Reddit on my iPhone. Of late, the only subreddits I cared for were on sports and their matchday threads and r/watches. I found myself aimlessly browsing through r/AskReddit and asking and answering pointless questions.
Your second to last point really rings in for me. You’d think with all the posts and traffic on Lemmy that there would be ad clutter or push for other internal paid brands, but it’s just so clean and only about the posts and comments.
