Interesting. But if you use your title in a context where the title is of no interest to the story or case, you should think twice. A professor is a representative of the University, as long as she/he use the title. It is not forbidden to tell your profession, but the title should not be used in a wrong context.
Regardless of this: Professsors have the right to express their opinions as everyone else has.
Perhaps they should have thougt of writing under a nickname…
There are a number of problems here. One has to do with the concatenation of details: “Yale hired so and so…and then five years later…and then when the contract came up for renewal…Yale let the person go.” Yale is now famous for doing that, to all tenure-track assistant professors, regardless of their extramural activities. Getting an assistant professorship at Yale is little more than a glorified post-doc., and people who apply to work there need to be cognizant of that fact.
The second problem has to do with academic freedom. In my university, as in most if not all Canadian universities, academic freedom is enshrined in a legally binding contract. I *never* “represent” the University–that’s not my job, not even when I work in it. I am hired to do specific tasks, and representation is not one of them. There is a Public Relations Dept. for that. Indicating my occupation on my blog does not mean I speak for the University, and academic freedom reigns regardless. My university is also quite proud to list the blogs that professors have, without endorsing their content. So we need to have a healthier view of what constraints professors work under, and not start heaping all sorts of unreasonable ones on top of them.
Using a nickname is a VERY BAD IDEA, and it is one sure way to get your blog dismissed by those looking to establish the qualifications and background of the author.
