Employee blogging

I liked the citation (sheet 2) of Joshua Allen:
As long as your company views your blogging as "you chatting with your neighbors on your personal time", you pose little risk. But the more that co-workers, CEOs, and so on are on-record as being cool with blogs, the more that blogs take on the timbre of being "official". The more "official" that blogs are, the more perceived risk the company takes on by allowing you to blog. And neither you nor your CEO is really keen to make things more complicated than they need to be. And this is why, IMO, you see most companies and employees today still dancing around the issue of employee blogs and seemingly settling on a "don't ask, don't tell, and please ... don't do anything stupid" policy.The issues of personal vs. business blogs (sheet 3, 5-7) is intriguing. "The extremes are not that interesting", indeed, as Lilia states. The interesting part is how we can mix personal and business blogs. I, for instance, blog about my work. But I make sure I don't post about confidential stuff.
However, I would like to have a blog (one blog) with which I could choose to publish a post internally (only to my colleagues) and/or externally (to the rest of the world). For every post you can set this setting: 'publish internal' or 'publish external'. I haven't seen blog software offer this feature yet. Wouldn't this solve much of the problems around employee blogging?
