I have always thought a meme analyzer (that would trace the spreak of info-virus-meme) would be great. This Blog Epidemic Analyzer is a step toward it. (via)

This is a demonstration website for our recent research (here and here) on information dynamics in blogspace. You may type in a partial substring of a URL you would like to track. For example compare slow, long running memes like "giantmicrobes" (i.e. www.giantmicrobes.com) or "spambayes" (i.e. spambayes.sourceforge.net) to short punctuated ones like "cnn.com" articles. Check out this page for some popular memes/URLs from that period.
