Last week, we launched ChangeTracker, an application that flags changes to whitehouse.gov, recovery.gov and financialstability.gov.

Since then, we’ve spotted a few interesting updates, but so far most changes have been relatively unsurprising. It’s time to widen the net and track Web sites that are more than just public relations vehicles for the administration.

So, we’d like your help! Where else ought the watchful eye of the tracker look?

Would you like to be informed when Facebook’s or Google’s license agreements change? Maybe a regulatory agency or an NGO would be of interest?

Please comment, e-mail or tweet your ideas!

(Also, have you copied ChangeTracker? The plumbing is freely available and dead-easy to use. If you’re using it, we’d love to know what you’re tracking.)
