In the "stupid is as stupid does" category, Wired reports that companies are blocking access to blogs as part of their standard security policies:
…companies worry that employees might leak sensitive material — perhaps inadvertently — while posting comments to blog message boards. In a survey of over 300 large businesses conducted in conjunction with Forrester, Proofpoint found 57.2 percent of respondents were concerned with employees exposing sensitive material in blogs. That’s higher than the portion concerned with the risks of P2P networks.
Communicators need to get engaged in setting clear policies and communicating them. What is even more ludicrous is the suggestion that blogs be blocked for reasons of "productivity over security". Technology companies, like Proofpoint, that suggest this should spend more time on the productivity benefits and articulating a value proposition around that.
