Failure of Personalization

A bunch of interesting articles and comments about personalization on the web:

• Column Two linked to this interview with Jared Spool: Purpose, not Personalization
  
• Gerry McGovern's take, a rebuttal from Stephen Downes and some elearning ideas from George
  

I'm still standing by my post from last month responding to Jay Cross's article on the topic -- personalization is hard because it's expensive and difficult to handle all possible variables, or at least enough variables to personalize properly.
