I check it every so often without logging in. A lot of the old major subs went dark and both All and Popular are almost exclusively memes. The occasional News or Politics article breaks through but, and this may be because I usually didn't visit All, it's like looking at a completely different website. The comments aren't too much different but it feels like desktop users are getting the upvotes now as opposed to the shorter but still solid replies from mobile users.
The fandom subs I frequented (Star Wars, NBA, etc.) have sort of gone to shit, though it's hard to tell how much of that was always there. Actually the biggest difference may be just how unmoderated some of the big subs are, so where before duplicate posts on the same topic would be removed in Technology, now you'll see 20 articles on the same thing. I suspect Reddit admins are inflating vote counts to make engagement look the same as always when participation is actually down, but it's just a hunch. I have no proof of it.
It feels like you see the same 5 popular subreddits get pushed on you either on r/all or your homepage. And if you visit any new subreddit you get spammed with posts on your homepage “because you’ve shown interest.” It all feels really desperate
IDK, nowadays I only ever use reddit desktop on my ipad (firefox on that forces desktop site everywhere) for a few of the naughty subs, but hopefully it won’t be long before they, too find out that most lemmy instances have an 18+ category too. I wouldn’t know.
