The cool thing about starting a new hashtag is if you do it in CamelCase (capitalising the first letters of each word to assist readers, as you always should), then when Mastodon autofills/suggests it, it will be in CamelCase for everyone.

Try it with one I started:

#AltTextIsWhereTheCoolKidsHangOut

@TwoClownsEating

That's Pascal case 😛

#PedantsRUs

@ratcatcher

I know, but it's close enough and camel case is easier to remember because it HasHumps.

@TwoClownsEating

That's the whole point: camels have lumps in the middle.

So:

benBlowsCamels = camelCase
BenBlowsPascal = PascalCase

@ratcatcher

Camels have humps not lumps.

@ratcatcher @TwoClownsEating

Didja ever notice that camels are self-mnemoniced? Dromedaries have one hump; Bactrian have two. (Lay the initial of the name on its back for the appropriate shape.) 😊

Edit: self-mnemonical?

"I'm not a pundit. I'm a pedant. Let me explain the difference to you!"

Sorry, sorry. One of my favorite quips, which I will bring out at the least excuse.
