On blogging while tenure tracking

I've had friends on tenure track at a research university, Penn State. One of my friends was borderline in his published research. His advsors said that his student reviews were too good. He was told that he spent too much time helping students while he needed to spend more time on research. His advisors wanted to see average student reviews instead of exceptional student reviews. He was borderline in regards to the number of peer reviewed publication per year and he was denied tenure.

Papa Beaver says that a research university might frown upon Assistant Professors spending time on a blog unless the respective Assistant Professor publishes twice as many peer reviewed articles than expected. Consult your local tenure advisers if exceptions apply.
