Google Sidebar

Google is releasing a new piece of software that could challenge both Microsoft and Yahoo, on various levels. The free program, known as Sidebar, presents consumers with a pane of customized information -- such as weather forecasts, stock quotes, news headlines, text feeds from favorite Web sites, photo slideshows and email alerts -- that sits alongside whatever else the user is viewing. It provides some functions similar to Yahoo's popular MyYahoo customized Web-page service.
