Here are four recent blog posts I found interesting:

• Harvard Business Review (HBR) blog’s guide to Obama’s State of the Union address.  A nice concise summary in case you are wondering what it was all about.
• mergers and inquisitions blog on the valuation of internet companies just before the dotcom crash and now;
• Felix Salmon on when disruption meets regulation.  The title says it all.
• from James Kwak’s blog, The Baseline Scenario, on the ingredients for a financial crisis.
