I've never heard anybody say they like these kinds of threads before. Maybe it's better on mobile, but Twitter makes it very difficult to browse on desktop.
Can we just have a sticky on every foone post on HN to tell people to stop complaining about it being a Twitter thread? Maybe then Foone himself [wouldn't hate being featured on Hacker News so much][0]. Not to mention he has a perfectly good reason to use Twitter threads (which he explains over and over): he has ADHD and it's a way to cope with it.
I don't really see how typing into Twitter's UI is any different than typing into a Notepad file. Just type the thought and hit <enter>. Any editing beyond that might be appreciated but isn't required.
For me they show up like that as well. But I still find that the format gives a weird stuttering to the conversation and adds so much "chrome" noise around the actual content.
In general I don't click twitter links on HN because I find the format painful for anything but short content. However I do make an exception for Foone as they have a lot of interesting stuff.
