Twitter is fucking stupid and has a limit on the number of characters you can use in any “tweet”.
My suspicion is that this is done intentionally so that users cannot properly explain themselves, which inevitably creates arguments, drama, and “engagement”. Mastodon also has this incredibly stupid limitation.
The result is that you end up with people just posting long rants as a series of Tweets (thread), rather than just one, thus bypassing the incredibly stupid limitation, while simultaneously making it super difficult to just read.
This website just gathers all of the tweets from this thread into one post that’s easier to read.
