For anyone wondering:

  ARPU: Average Revenue Per User
  ARPPU: Average Revenue Per Paying User
  MAU: Monthly Active Users
  DAU: Daily Active Users
  MUU: Monthly Unique Users

Interesting side-note: The word DAU means something completely different in German.

  * DAU: dumbest assumable user / Dümmster anzunehmender User

The abbreviations take just as long to say out loud as their meaning.

Not in German they don't :-) I actually use the company with the longest name in the world as a test for validating web input forms.

Donaudampfschiffahrtselektrizitätenhauptbetriebswerk- bauunterbeamtengesellschaft

which is "association of subordinate officials of the head office management of the Danube steamboat electrical services"

It also tests that you handle the high ascci characters properly

No, you say them as words to sound like a child. "What's the mao over the dao (tao?) versus the are-poo?"

i wonder how ping me belongs with the "jokers". seeing that i can picture many people like me using ping me all the time, but having never heard the term arpu
