Do you have a dress code policy at your place of employment? Do you have an acceptable Internet Use Policy? Do you have a corporate blogging policy?
That last statement probably brought you up short, because most IT departments and corporate lawyers treat blogs like a bad case of the shingles - do nothing and hope that if you do get the itchies, the pharmacist will have something to clear it up with minimal pain and scratching.
But it doesn't work that way.
DoAskDoTell has a great description of corporate blogging policies.
Charlene Li of Forrester really helps drive this issue.
Yahoo and McDonald's do a good job, also.
If you are a company that has employees, then you should have a blogging policy. It does not matter if you don't like blogs, or don't ever plan on using them. What do you plan to do if some of your employees are writing about the company right now? You could fire them (we call it getting 'dooced'), but there is the problem of firing someone for an offense that 1) could be protected under the law, and 2) isn't listed anywhere in your employee handbook as being wrong.
The first thing I ask any corporate prospect is whether or not they have a blog policy in place. The 2nd thing I ask them is whether or not any current employees are blogging (and I never, never tell them the answer to the 2nd question).
