aideRSS: Analyze and Rank Blog Feeds

I'm not sure what to make of the aideRSS blog/RSS analyzer. The first thing I did was put this blog's feed into it to analyze. It gave each blog entry a numeric score between 0 and 10 where higher numbers indicate a higher scoring blog item. It seems to create a score based on some kind of comments (apparently not the same as comments attached to the blog) and whether or not the blog item is picked up in Technorati, del.icio.us, or Bloglines. Although I still don't understand its ranking system, it is somehow always fun/interesting to see even apparently meaningless numerical scores :-)
