1. Clicking on a link now takes you to the comments page, instead of the destination. To get to the destination, you need to hunt down the "direct" link. This is a shitty pattern.
2. The spacing is all weird. I just don't like the design aestheticially. But it might just be "it's different and therefore bad".
3. A lot of features aren't yet implemented on the new platform. (Crossposting, at least.)
4. Some content that I want available immediately (my multis) are loaded asynchronously, forcing me to wait before I can actually go to where I want.
5. Infinite scroll can fuck off and die in a fire. It's less of an issue on reddit, where bookmarking a given page doesn't really make sense anyway, but in principle I want my content paginated so I can have a sense of how much I've seen so far.
6. Collapsing threads is now slightly more annoying than it was, although it might be another case of "new and different therefore bad".
Some of these aren't really relevant to a link to a specific thread from outside reddit.
It's a lightbox-infested mess that badly reimplements browser features like "tabs" and "back button" with so much needless JS that my laptop's fan goes to 100% of rated RPM.
Also the design takes up lots of screen real-estate with cutesy useless features.
Personally I feel it is optimized for constant dopamine and advertisement, at the cost of content density.
Previously, I could navigate to a subreddit, relatively quickly glance at whether anything was new, without being distracted by autoloading images and videos. Now reddit looks more like ebaumsworld 10 years ago.
If you’re not on mobile, it takes for me like 4 times as long to load a page. And there’s all kinds of dark UI patterns to prevent things like linking away from the site or even searching the site.
How it looks, how it behaves, how it performs. If they implement it, I will finally be able to break the addiction, and will probably sell off my 11 year old account.
It breaks keyboard navigation in some cases that I've been unable to identify why. I think that the new style of loading pages in a div on top of the underlying page sets the focus wrong or something but often pgup/pgdown will not work.
