We've posted a couple of items about the new Google Home Page API in the past few days but I've mentioned (my bad) that Microsoft has been allowing developers to to build "widgets" for users to easily place on to their Live.com personalized home page for several months.
The most viewed widget at the moment is one to place Virtual Earth onto your Live.com home page. Other
widgets that caught my attention during a quick browse included a "to do" list, access to Indeed.com, a Daily Dilbert, a Bay Area Traffic Map, ShipmentTracker, Word of the Day, and many many more.
Oh, and if you just must have a Google web search box nearby, no problem. I also noticed a widget for a Google search box for the MSN Live.com page (that also includes an MSN Search box).
