If you have loaded up www.google.com today, then you would have noticed the "iGoogle" link in the top right of the page.
You can now set up a fully customized home page for yourself. With custom news and weather. This tool is called "Gadget Maker".
Kinda strange that they have taken so long to mature this service, since www.excite.com has had this feature for years.
The nice thing is Google detects your location and delivers custom content based on where you are. Not like other personalized news portals where you end up viewing tons of rubbish before you have fully customized your view of the world.
Well done Google!
