First, what program do you use to scrap/save with? Once I know this, I will be able to help
In PS or PSE, there is a "save for web" feature that works very well to preserve sharpness when resizing for the web.
Honestly, I don't see much blur on your pages, though. Could your screen resolution have been changed accidentally? I only ask because it's happened to me before, and everything looked blurry to me
