Can't tell if this is serious. Is this feature designed for hipsters? What is the percentage of the population that knows Morse code?

If I recall correctly this was published as this years April Fools by the Gmail Team.

What is supposed to be there? I only got a 404 error page.

Wow is this from April 1st? These guys sound so serious!

This was an April Fool's joke from earlier this year.

Is it bad that I want this?
