@jcsteh @juliette @joachim There's quite a few examples of all lowercase hashtags being misinterpreted. Eg. When Margaret Thatcher died and "Thatcher is dead" was trending, some people thought it meant that the singer Cher had died:

"Have you heard #ThatcherIsDead" versus "Have you heard #ThatCherIsDead"

(For those who can see it, I've used Pascal Case above for the benefit of screen readers but imagine it was the all lowercase #thatcherisdead instead).
