We have three contests for a reason. First, it gives us three opportunites to have winners and their entries bask in the spotlight: The Etech, Open Source, and Mac OS X conferences, where the announcements will be made and the receptions will be held. The software will promoted on the computers in the Rendezvous Lounge at each of those events.
Also, for those who didn't win in the first contest, it gives them another chance to go back and refine their application and possibly win the second or third time around.
Even though each contest (or round) is a distinct event with distinct winners, it's a chance for all of us to learn how to evaluate, adjust, and compete again.
Personally, I feel really fortunate that we're able to have the Innovators contest run for essentially 7 months, with awards and recognition along the way.
Remember, not only are we competing with each other here, the bigger picture is that we're learning how to compete with developers from other platforms and with the computing industry as a whole.
We're trying to help Mac developers succeed in an number of ways, and this contest, hopefully, will prove to be effective.
