Old.reddit UI fills the entire width of the screen, and default view is compact. You see more of the feed at a glance without having to scroll as often. When it comes to comments more of it is displayed when it comes to nested comments before clicking.
New reddit takes up a lot of space. And clutters up the side with stuff like related posts when you check the comment section.
Another big one is reddit enhancement suite which lets you tag and block things only works on old.reddit.



I stayed away from the general popular subreddits that tend to populate /r/all preferring to stick to either hobbyist and tech related subs. I haven’t noticed much change when it comes to places like emulators or roms for example mainly going there to check the wiki and when myrient went down people backing it up and making Minerva.
So I guess if it is the general trash subs that the twitter crowd congregates along with news, the bots and stuff might be more apparent with it being about karma, trying to go viral, and manipulate what users see. But, the more resource oriented ones like Linux or buildapc still seem to be less affected with people there just trying to help out.
