Of possible use for general counsel and other in-house professionals, many blogs concentrate on compliance-related topics, which includes ethics, corporate social responsibility (CSR), and corporate governance (See my post of Oct. 7, 2008: ethics with 29 references; June 11, 2008: compliance with 33 references; and
Aug. 17, 2008: corporate governance with 18 references.) Here are 16 of them I have located (but have not examined); I welcome guidance as to other blogs I have missed.
