You have a tremendous amount of information, a bevy of ads, a long list of tiny links, and a number of *very* large images. A user on FF, or Opera -- with a dial-up modem-- isn't going to wait around for it to load. At best you've got 8-sec to grab 'em. On IE, even if they wait, they'll have a hard time sorting, and reading.
Here's how Douglas Bowman, faced with hundreds and hundreds of pages of like material, solved the problem for Wired News-- including text-zoom on *any* browser, with x back through NN4, at any screen size resolution (on any OS). And no horizontal scroll.
Amazon.com, as well, handles an unbelievable amount of
informaton. Well organized. Loads fast! Easy to read. No need for a horizontal scroll.
Now I know a blog isn't the same as Wired News or Amazon. The similarities though to what you, and your users face-- that's what is important. Lots of information, lots of ads, well organized, fast to load, easy to navigate, and a pleasure to read-- even, if you must, on IE.
You can do it, too.
