Microsoft Live Labs Listas
Listas is a tool for the creation, management and sharing of lists, notes, favorites, and more. It allows you to quickly and easily edit lists, share them with others for reading or wiki-style editing, and discover the public lists of other users. We encourage you to try using it for meeting notes, bookmarks, shopping lists, to plan a night out, or whatever other creative ways you can think of.
In the Listas Community Section, you will find a number of highlights of the most popular and random items from around the community of public lists such as the most used tags, the hottest lists, and prolific contributors. You can even add others’ lists (or any RSS feed) to your own Listas so you are always up to date.
The Listas Toolbar lets you grab contents from pages as you are browsing.
