Raj Jain stops by from Live Labs to show me their latest technical preview. Listas is a list management system. It's a way for you to create lists of anything you like and store them on a central place. You can invite others to participate in your lists, and you can publish them to the web or an RSS feed.
You could keep a real time grocery list online, invite family members to add to it, and subscribe to it on your phone. You could use it as a to-do list and feed it into your Sidebar using a PopFly RSS block.
Listas also has some nice template features to make it easy to build lists from search results and web sites you browse. It's in the process of going online now, so go give it a try.
