Interesting juxtaposition of headlines today.

On the one hand we have Gerald Levin, the former chief of Time Warner, taking responsibility

Ben Bernanke

for "the worst deal of the century," the company's disastrous merger with AOL. (He was appearing on "Squawk Box" with the other major figure in that ill-fated union, former AOL chief Steve Case. Check out the full comments here).

On the other hand, we have Fed Chairman Ben Bernanke blaming lax regulation, not the central bank's low interest rates, for the housing bubble. These comments, of course, come as he awaits the congressional go-ahead to serve another term as the Fed's chieftan.

Responsibility and blame. Just thought I'd point that out.
