> That cheating is so easy on Coursera, "give me an A" is precisely what's going on for people that are there, not for the learning experience, but for an A.
Maybe the 'A' or nice cert is there for some people, but no one that I know personally cheats for the grades on coursera. OTOH, all 7 of them are currently well employed software engineers, so maybe the incentive to cheat just isn't there for them in particular. Until the signal gets gamed, I think it will be useful for hiring. Further, it's pretty verifiable if the interviewer has also taken the course. What did you think about the programming assignment about X for course Y, how did you do Z? Throw in fake X for real Y if you are particularly suspicious. If you've cheated through it, it's gonna be obvious.
