I’m really not sure what i think of all this. I mean, you are showing examples where sites are using 3 different fonts (for bold, italic and normal… what the heck?!).
OK, i have to admit that this articles contains useful informations. But those problems don’t even have to exist if webdesigners would think twice before using fonts and script in masses… from external servers. Then 95–100% of all Top 1000-Websites wouldn’t even have to think about preloading.
