Changes Meter

Changes Meter is for you if you need to check a Web page or a local file frequently, looking for changes.

You know it's boring, error prone, and a real waste of precious time.
Several Web sites offer RSS feeds, but they do not necessarily cover the type of information you are looking for, and there aren't many tools to check local files.
Changes Meter does this exact job for you and it will notify you with a colorful, useful, and unobtrusive pie-chart icon on the menu bar.
