Last week, I explained how to use social networks as a way to help supplement your reporting. I'd now like to introduce you to a relatively new tool that will enable you to aggregate your social network information, and all of the information on your friends' networks, to keep track of what virtually everyone is doing.

The site is called Spokeo, and I can guarantee that the first time you try it, you'll want to completely dismantle all those social networks you've spent the last week building.

To get started, you'll need to create a free account on the site. Right now, it only works with free accounts such as Hotmail, Gmail and others.

Spokeo will then scour all of your address books for the email addresses you have stored. It'll then cross-reference those email addresses with dozens of social networking sites...even Amazon wish lists!...and will create an RSS-style feed for each of your contacts. Any time that one of those people makes a move, updates her information, you name it - you'll be notified.

One of my colleagues interviewed Noam Chomsky a few years back and still had his email address stored in his address book. We now know all of the books Chomsky is hoping to read in the coming months. I have a few old Hotmail accounts that I haven't used since college...but when I entered them, I was able to start following old professors and even old boyfriends.

Can you imagine how Spokeo might be an incredibly powerful reporting tool? The possibilities are virtually endless...
