I just wanted to see what's new on my homepage in twitter, but after scrolling enough, the algorithm started to glitch out, and show me stuff I'd seen before.
I saw the same tweet thread for like 3 times, and the page visibly flickered, changing the visible tweets.
If only I could follow twitter people from Mastodon, but I imagine twitter wouldn't be too happy about that.
Here is the "flickering" I was talking about in action.
(ps: Why doesn't Mastodon support MKV uploads?)

Unwanted Update: This is still happening 6 months later.
You'd imagine a company like Twitter would fix this by now, but I'm not sure if they are aware of it at all.
