Whaddayaknow, maybe Alexa is the problem! Compete.com shows exactly the opposite trends with increasing 2007 traffic to all the 2.0 sites mentioned. (http://snapshot.compete.com/techcrunch.com+technorati.com+gigaom.com+)
Is there any consensus on which of these sites (Alexa or Compete) is more reliable? Or at least...less unreliable?
