Interestingly enough, my employers seem to regard Perlmonks as a blog.
I recently posted to a recent thread on consultancies, where I named and linked to my employers' website. I received a call from my manager, who it seems had received a call from the corporate blog police. Apparently, there are guidelines about what individuals are allowed to say when posting to their own blogs. This was news to my manager too. I wasn't saying anything bad about my employer, quite the contrary in fact.
The simple resolution was to remove references to the company name of my consultancy, and remove the web link. It was probably through http_referer that they picked up the reference.
