Congrats to our friends who created the personalized homepage -- today they released an API that lets you create modules that people can add to their Google homepage. It allows for pretty interesting modules by letting you wrap your existing web content, apps, or mashups, and the development team will be reviewing all the modules submitted.

For more information, check out the Google Homepage API page and be sure to join the Google-Homepage-API Google Group. You can also take a look at the module directory that includes some modules the team created to help get the ball rolling.
