However, I do take most certifications as mild negative signs. E.g., SCJP, CSM, PMP. A lot of for-profit certifications are worthless. A notable exception are some of the Cisco certs, which really put people through their paces. Which makes sense, as Cisco benefits more from having expensive Cisco products work well than from certification revenue.
It'll be interesting to see what bucket Coursera certs fall into. They need to jump on the cheating thing right quick, though.
