I have no idea why, but I can only stand to use reddit in "old" mode. Even on mobile. It's completely 100% unusable in any other format. I've tried to use their app and standard mobile website, but I can't make heads or tails of the hierarchy of content.
There could be a userscript for a better reddit UI if someone cared but looks like nobody does. There's also Reddit Enhancement Suite but I don't think you can use it on mobile.
Wasn't there something called `teddit` that was written in nim that did a better job of removing all the js crap that makes reddit terrible?
I would imagine everyone will just move to that if possible. Although perhaps that may also be affected by their idiotic API charge junk.
If you don't use old mode in a mobile browser, they block off 1/3 of your screen with "Are you sure you don't want to use the Reddit App?" Pretty sure I don't Reddit.
