I would like to see it on the resume of an otherwise unskilled person or a person with skills in another area as it demonstrates interest in our field. I would not be impressed to see it on the resume of a developer or web designer, though.
I've listed all the coursera courses I have taken at the end of my resume, in one line. I think it shows that I believe in teaching myself new skills all the time, on my own time, without needing an employer to train me. But it doesn't have much value beyond that.<p>Given two candidates of equal skill and experience, I would hire the one candidate that still likes to learn new things on their own. It's a good trait in a developer.
For a junior developer or a recent grad then absolutely. Granted it's not an indication of phenomenal ability but it's a clear indication of effort and eagerness to improve yourself.
