Yep, I agree. Was just talking to my wife about Reddit. It's so slow now, especially on mobile. The page constantly crashes on my Android phone and they always recommend the app. No thanks.
Today is the day I decided to switch to old reddit... My Mac can run garageband and vsc and 40 chrome tabs at once, but as soon as I click a front page Reddit link, that modal is like pouring sludge into my computer.
Well, I certainly also do not tolerate the delays in contemporary React sites either. Take Reddit for example, which used to be lightning fast when it was mostly serverside, which now is painfully slow, especially on mobile.
