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.
I joined reddit in 2011 and you get used to things slowly filling up :) the fediverse will hopefully experience the same evolution
I wouldn’t have been that far behind you, I think my first account was 2012/2013.
It did feel a lot more established, like I could find communities and posts about anything. It’ll just take time but heavy uptake is essential.
