I just installed IE7 and this blog looks quite broken using that browser. Local development copy of the site looks fine though so I think it has to do with IE7 refusing to load CSS, JS, and image files from my site, probably something to do with P3P crap.
I am rather sleepy just now so I'll have to look at it in the morning. Urgh.
Update:
It's fixed now. HTML base tag was not working somehow on the remote site. More details in the comment.
Update 2:
Heck. My wife wants to drink some wine before bed so I have time to describe the odd behavior.
As you can see from View Source of this page, this page has a <base> element in its <head> element and it is set to http://www.docuverse.com/blog/. Now the page URL for the front page is http://www.docuverse.com/blog/donpark/. Now CSS, javascript, and image elements used relative URLs. For example, the feed icon's relative URL was "images/feed-icon-12×12.gif". Combined with the base URL, the feed icon's full URL should have been http://www.docuverse.com/blog/images/feed-icon-12×12.gif but when IE7 was attempting to fetch the image from http://www.docuverse.com/blog/donpark/images/feed-icon-12×12.gif. Notice that the page URL was used as base instead of the one in the base element.
Did I misread the spec or is this an IE7 bug? What's even stranger is that, when exact same content and code is run on my local machine, IE7 had no problem.
