Lists

Another Microsoft tech preview item is Listas.

Create and edit lists, keep a list to yourself or share it with others and collaborate with your friends. Collect content from all over the web with the Listas Toolbar.

I'll be trying it out. Right off it sounds a bit like Microsoft's tool to compete with Google Notebook.

Organize your notes.
Keep all your notes organized by creating multiple notebooks for different subjects or by dividing a single notebook into several sections. You can also easily rearrange your notes by dragging-and-dropping them from one section or notebook to another.

Add your own thoughts.
Click the "New note" button and start typing to add text notes to your notebook, or click the "Add comment" link within a note to add comments to clippings you've collected.
Search the full text of your notebooks.
Easily find any information in your notebooks using the search box at the top of the page.
