Their new, but not really new anymore, redesign is so adversarial that the site is frustrating to use unless you use the old version or a different mobile app. Comments section cut off by a news feed, nested comments require loading a new page, but going back doesn't save your location because it was collapsed to show the news feed. The news feed preload lags way more. The new search basically has never worked.
It basically feels like you are constantly trying to fight the ui to show you what you want while trying to dodge the buffet of churned content they throw at you to try and keep you in the social media vortex. Like everything else that becomes mainstream popular, the demographic has shifted away from people who care about these things.
