Web is changing (really? 🙂 when ;)) you can check more and more web sites changing to a new look at microsoft. Maybe one day others will do too.
See http://www.microsoft.com/silverlight/ or http://www.microsoft.com/ or http://www.microsoft.com/design/Culture/Master.aspx and on the other hand http://www.microsoft.com/windowsvista/ or http://office.microsoft.com/
new clean, easy to find and easy to navigate sites but including new ‘feeling’.
Yes others Corp have changed, but in my opinion they have upgraded the technology, not a rework of the concept
Check http://www.archive.org/web/web.php for some examples.
Maybe, this is something Microsoft Office SharePoint Server 2007 is going to accelerate:
Go for it!
