Should programmers be middle managers?

Recently, I wrote about whether programmers should get an MBA here, and said that an MBA would be helpful for the programmers who wanted to get into management.  Related to that, I came across an article on CIO.com about the inherent skills needed for programmers, middle management, and executives.  I don't have any particular insight into the article, or what it means for I.T., other than it's an article worth reading.  I think I might put the book on which the article is based on my reading list.
