Why is this split into <i>7 pages</i>? I could understand maybe splitting it up into 3 pages to get more pageviews, but this is just going to irritate of every single one of their readers. Not to mention that the article fails to address the very significant issue of font rendering, and how bad it can be on Windows without ClearType enabled or special hinting larger font sizes (which is resolved in IE9 and Firefox 4, neither of which are released yet).
Just to be honest: the design of the site makes me want to ignore whatever advice it might contain. It doesn't really scream "I know a lot about great looking typography, layout, or web design."
Thanks to both for the clarification. I will take a chance to test this more in detail with a couple of virtual machines (since I use Mac) perhaps tomorrow or as soon as I have some time; does the library I liked here and in the post solve the issue? I admit I tested it quickly (say 5 minutes or less) with Windows VMs, but at that time everything looked OK to me using that library, since the custom web fonts were disabled (and replaced with the closest similar web-safe fonts) on for example Windows XP with Clear Type switched off so avoid the bad rendering in those conditions.
