We have added a host of new features and improved designs to Listas today. A fresh home page design and updated community page make finding relevant information even easier. New community lists like popular tags, recently created lists, and top users are all now available both in Listas and through RSS. For fellow GTD fans, there are now task lists. Improvements to printing support, history and version management, and many other additions and refinements round out the update. You can check out the newly updated Listas technology preview as always at http://listas.labs.live.com.
