Aha. 'Because I went there'. If your initial hires (presumably from your personal network) were from similarly highly ranked schools, then you have a strong correlation between social networks and school strength. Note that when no one knows the hire, school strength turns out to be irrelevant.
What about Google building this into the Chrome app?
When you launch the app for the first time, it could ask "Do you want to open URLs in Chrome by default in Chrome-enabled apps?", and make it possible to change this in Chrome's settings menu.
This setting could then be stored in a UIPasteboard named something like com.google.chrome.default, and apps that want to implement the functionality suggested in the original post would just look in this pasteboard for the current setting.
According to Apple's documentation, "The UIPasteboard class enables an application to share data within the application or with another application using system-wide or application-specific pasteboards." http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/...
For a couple examples: OpenUDID and SecureUDID use UIPasteboard.
This is great. Especially with services like Parse out there, I could see how a sufficiently motivated/creative person could start from zero programming experience and become a skilled iOS developer in the course of a summer.
