The Reddit and Twitter web apps are actually great on mobile, but they lock you out after a few minutes. I used to use both all the time until three or so years ago when the constant app pushing made both unusable.
- Time to load a twitter link: 14s (20s to display a preview of the picture).
- Same link on a nitter instance: 5s, page fully loaded, with replies.
Also, less than half the page is dedicated to content, I have:
- a search bar
- log in/sign up
- Cookies notice
- "Twitter is better on the app" "Not Now/Switch to the app" (that one takes a lot of space).
All of the above keeps floating above the content, so I can only scroll through a tiny window. The content is lazy-loaded, which makes scrolling annoying. A lot of space is wasted with buttons that are only useful if you're logged in.
The experience is terrible on mobile, and it's mostly the same for reddit.
Use nitter, libreddit, invidious, bibliogram (is that one dead?) and others.
It's a shame that these big companies seem to suck at making usable websites. They probably chase "conversion" to new accounts at all costs. And that probably works (A/B tested).
