I really like the social bookmarking/tagging approach to keeping track of stuff on the internet that Del.icio.us championed. While "Live Favourites" has been Microsofts online Bookmark Manager, its never really been able to offer me the features I need to make me stick. Today we annouced the Microsoft "Tagspace" service and I'm going to start paying with it (just noticed that only URL's on Microsoft.com are supported at the moment).

While you are checking out new stuff, dont forget to look at the AWESOME new Windows Live Search 3D maps, very very impressive.
