The Obama iPhone app.

IPhone apps are cool, but is it a little creepy to embed a politician in the hub of all your communications?

The most notable feature "organizes and prioritizes your contacts by key battleground states, making it easy to reach out and make an impact quickly," according to the software.

On my phone, the application ranked contacts in Colorado, Michigan, and New Mexico at the top; at the bottom was a friend whose cell phone has a Texas number, though she actually lives in California.

The application anonymously reports back the number of calls made this way: "Your privacy is important: no personal data or contacts will be uploaded or stored. Only the total number of calls you make is uploaded anonymously."

I'm just tech savvy enough to get paranoid when I read assurances that I shouldn't be paranoid.

Taking the assurance as true, I still wonder why the campaign records the number of calls. Are they trying to determine which of their supporters -- identified by number -- are the most active social communicators?
