It depends on the field and what you want to do with the degree. I've sat on a lot of search committees for academic jobs. Graduate degrees from online schools don't hold a candle to brick and mortar graduate degrees for academic jobs. I used to teach for University of Phoenix. I don't know how their Ph.D. programs work but for undergraduate and master's level courses, they had absolutely no full time faculty. Unless things are different at the doctoral level it's hard for me to imagine how someone could be a leading expert in a field in which his work was just a sideline.
