Live.com is replacing Google in my affections as my first-line search choice. Substantively, the searches seem a bit more precise, with fewer extraneous hits near the top of the list. In the long-term, as the volume of noise on the Internet grows super-exponentially (if there is such a concept), excluding becomes as or more important than including.
Also - LIve has great pictures as background, every day a new one. Run your cursor over the picture and various mini-window pop up, with links to information about the site. Today is Wyoming's Devil's Tower. As I said to a colleague recently, the great thing about the Internet is that it makes procrastination so efficient.
