iGoogle is sometimes used as a framework for an individual’s PLE, since it provides a convenient and readily accessible “container” for a range of widgets and content items which can easily be added and removed. It is also relatively open in the types of widget and content that can be embedded.
My iGoogle page is here… I occasionally have it up on a secondary computer as its convenient to have the calculator, search functions and quick links to my Google calendar, contacts, e-mail etc. I also like the world map with sun shadow widget which can be made full screen on the secondary computer screen which is a nice. Better than buying the $3,000 executive version 🙂
