Using the old version of IE, v.6.0 here.
Didn't have much of a chance to try all of the features of the site, or look at every bit of script.
However, on first glance I would like to say that;
1.) The graphics and presentation is/are very nice. Looks clean and sexy. Impressive.
2.) Works well in 800 width and above, no problems with any resolution, so good.
And the only suggestions so far would be;
1.) As I am using an older browser at work with no extra addons, so the RSS links on the left do not work for me. Perhaps place a mouseover message that older browsers may not be able to use these features.
2.) For accessability, the text is not re-sizeable. This isn't a problem in later versions of IE, as there is a zoom function, but for older browsers there is no way for the user to make the text size larger.
All in all though, a good job!
