I have been playing with the the Ginger release of Netvibes. Some new widgets and customization available in this Ajax-powered customizable startpage.
Some new eye candy along with new & improved widgets offer improved multi-language support and integration of social networking accounts.
Netvibes has been my Firefox startpage for nearly 2 years now and I have been pleased with the direction they are taking with private/public page customization. I like the idea of a Ginger-like PLE. I have set up a Netvibes Universe tab as a PLE for a practice for which I am still a young padwan – parenting.
