I thought the "I'm Feeling Lucky" button was like an advertisment, you know, like "Claim Free Xbox" or "You won an Ipod" so I never clicked it. Oh and haha, look at Yahoo back on 1996 http://web.archive.org/web/19961017235908/http://www2.yahoo.com/
I liked the simplicity of the site and when they were feeling really crazy they would change the Google word to reflect their mood. I'd go to Google just to see if there was something different about the word that day. My favorite so far has been their chinese new years.
I still can't believe how quickly Google destroyed its competition. You never even see those "Yahoo!!!!!!!!!!!" ads on TV anymore. A few years back they were everywhere.
