ChangeTracker

Last week ProPublica launched ChangeTracker, “an experimental new tool that watches pages on whitehouse.gov, recovery.gov and financialstability.gov so you don’t have  to.” Every time a page at one of those sites changes, it visually shows you what’s different. They’re using Versionista, a service that lets you do that with any Web site. Even better, ProPublica explains how you can do it too.
