Microsoft released Listas : All your lists in one place

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.

You can use it for meeting notes, bookmarks, shopping lists, to plan a night out, or whatever other creative ways you can think of. Possibilities are limited by your imagination only.

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.

You can even create lists from all the things you find on the web, like search results, wish lists, videos, or all or part of virtually any page with the Listas Toolbar for Internet Explorer:
