One change found on whitehouse.gov by our ChangeTracker was the removal of direct criticism of the Bush administration's handling of Hurricane Katrina.A few weeks back, we launched ChangeTracker, a tool that keeps an eye on White House Web sites and sends alerts when a page changes. We've used it to find a few interesting changes to whitehouse.gov, but we're hoping to hear what you've done with it.

The day ChangeTracker launched, we also wrote up instructions on how you could duplicate it, in the hope that you would set up change trackers to watch other Web sites. This seems to have been a success -- we can see via our logs folks have copied our code more than 50 times.

But we can't see what sites they've chosen to track. (That point was driven home when we found out that our own, industrious Paul Kiel had set up a tracker without telling anyone.) So while we've been tickled pink by the success, we realized that we should probably ask:

How are you using ChangeTracker?

We'd love to highlight interesting uses.

Hope to hear from you soon.

P.S. If you’re new to ChangeTracker, please do give it a try.
