#33 on Blogdex?

According to Blogdex, my blog is ranked #33 on the list of "most contagious information currently spreading in the weblog community".  Huh?  I know I have many readers and my posts get linked widely even crossing language boundaries, but #33 seems rather high up.

Update #1: I am now #79 after being #33 for over a month.  If the ranking is purely based on how widely memes spread, I think this is about right.  While amount of traffic I get is not among top 100, I do tend to post original and often viral memes.
