@Curator Quick not about this:
Capitals in hashtags help people who use text-to-speech with Mastodon because the TTS can see the words and pronounce them better (and capitals also make reading hashtags easier for humans too).
Think '#youcaneasilyseethewords' vs '#YouCanEasilySeeTheWords'.
But... The web interface's hashtag autocompleter removes the capitals even on hashtags it knows about!
So do make sure you keep these capitals in / put them back in!
