I check my referer log occasionally (well, actually the version of it produced by sitemeter); tonight, I noticed that one of my referrals came from an a9 search for the term “2000 movies”. I was curious, so I reproduced the search, and found that one of my blog entries from December 26, 2000, titled “Movies, Movies, Movies” was the second result in the a9 search (powered by Windows Live).
I think they have a bit of tuning to do on their algorithms.
