MSN's Tabbed Browsing

In a future post I will talk about some of the challenges relating to building Tabbed Browsing as an add-on to IE.

The MSN team has taken on this challenge, and their latest toolbar adds tabbed browsing to "older" versions of IE. I haven't used this toolbar enough to comment on the functionality, but I've seen some confusion in the community and I want to clarify that this is a separate effort from IE7.
