The Freakonomics authors have taken their blog to the NYTimes - it will be interesting to see if the Times is launching a broader Huffington-like strategy of rolling up on-brand blogs.
Personally exciting (besides the fact they are now making videos as well) is that I'm included in their "Smaller Blogs/People We Like" section (i think i qualify for both). Way below the fold but I ain't complaining ;-)
My only beef is it seems their feeds have gone to summary mode as opposed to full text. I understand the economics of this since feeds are difficult to monetize but as a heavy Google Reader user would prefer everything delivered to me.
