I noticed some nice useability improvements in webmessenger today, at first glance I noticed:

• New look-n-feel graphics
• Better authentication integration with Hotmail
• Ability to start webmessenger in a pre-determined mode

It's still missing the ability to maintain your messenger icon.

One thing that I did discover this week was that you can change your messenger display name in the web client by clicking on your name to make it become editable.
