Yes it will be interesting to see three things once it's released:

  1. How many people will use it initially (ive seen 1000-2000 people on the beta at any one time)
  2. How many people will use it in a months time (I'm pretty sure in the white paper they said a huge percentage of people stop using apps after the first month)
  3. If lots of people use it will it run smoothly - not crash :P

Thanks for reading my other post as well :)
