Should you reveal personal information on a professional blog?

On the Contentious blog, Amy Gahran is running a survey, and I found reactions to Survey Question 1: Is Personal Info Ever Appropriate? intriguing:

The big news here so far is that the often-touted perspective, “No one wants to find anything personal on a professional site or blog,” (which has been directed at me personally quite a bit lately) appears to be completely wrong. The people who prefer a “Berlin Wall” between the personal and the professional comprise a distinctly small minority of the online audience for business sites or weblogs.

I guess I'm in the minority. Go figure. :-)

I enjoy reading a little -- a very little -- about the personal life of bloggers who are blogging on professional blogs. In general, however, I think that if you're writing a blog which is dedicated to a subject you should stick to the subject.

If you want to talk about your personal life, or other topics, why not create additional blogs? If you're reading this, I assume that you're interested in writing, so that's what I talk about here.
