If you were hanging out on Meta.SO yesterday, you might have seen Alex Miller (no relation)'s post about a potential new Stack Exchange service for 'matchmaking' between developers and potential beta testers.
If you missed it, I'll summarize: We've got a community of talented iOS and OS X developers hanging out on Stack Overflow, and a committed community of power users and enthusiasts hanging out here on Ask Different. Doesn't it seem natural to provide a way to help people interested in testing new software and developers in need of alpha and beta testers find each other?
A program like this would be completely free and strictly opt-in for both developers and beta testers.
So: would you be interested in participating in something like this?
If you're interested in getting this program started, please see this post where I request aid in putting together an ad to promote this idea!
Update (Summer 2011):
We are looking to start rolling this project forward. If you are interested in beta testing an app, please fill out this form.
