The new Mailbox app from Orchestra, Inc. is showing a different way to run a beta of it's product and it's actually a lot of fun with complete transparency!
When you download the app, it reserves you place in line. I'm guessing most sites that are in beta do the same thing but to me what is different about this is that they actually display your place in line with the number of people in front of you and the number of people behind you.
Opening the app will count down from the last number you saw to your current place in line. I've seen it move only a few hundred spots to moving over 10,000. The incredible thing is that I check the app every few days just to see where I am in line.
I am guessing there are other apps or sites that have done similar things however this is my first experience with this sort of process in an app and it's nice.
I'll write up a summary of Mailbox after I get it installed but I already have had a positive experience with what I should expect from the app based on the user experience so far.
