* It'd be great if it was more clear that Microsoft itself was behind the site (there's just one little logo at the bottom left).
* The home page seems targeted at developers. It'd be great if they had another page targeted specifically at end users spelling out in clear terms why a.) it's bad for them to still be using IE6 (e.g. throw some scary warnings about viruses in there) and b.) what they can do about it (e.g. upgrade or install an alternative browser if upgrade not possible.)
* Now that I think about it, they need another page like the one above but targeted at enterprises. Again, lay out in clear terms all the horrible reasons for using IE6 on the open Internet. Convince them to install alternative browsers on desktops for general browsing and to restrict the use of IE6 to only those specialized applications which absolutely require it.
My wish list is probably already three items too long, so I think I'll quit while I'm ahead.
