I have intentionally been very careful not to reveal any specific details about my employer and or job because I just don't want to have to deal with this. I find much of this to be truly distasteful.
By much of this I mean that to include internet and email policies as well as blogging. It is the impingement on my ability to express myself that irks me, but at the same time I recognize that due to liability issues few companies if any will allow an anything goes environment.
But during these early days there is a real problem in not having clearly established policy.
I do not agree with the doom and gloom crowd that says that this is the end of free speech. To begin with, if you are blogging at the office there are a multitude of issues and ethics involved in that, not to mention that you are telling your IT department and company all about your blog. In effect you open yourself up and invite comment.
It is possible to blog from other places and to speak about the office, but you have to be careful with the details and specific information in your posts. Nothing profound there, just common sense.
