I am grateful to have learned about the existence of Coursera. It provides me the chance to branch out and advance my knowledge in new fields without strapping me down to a course...if I find a new area of interest, then that is great, but if it turns out that the topic Ive selected isnt something that truly holds my interest, then Im not left with the sense of obligation to complete a course just to rationalize having spent my money on it. I go out of my way to take part in the surveys throughout the courses because I feel an obligation to give back to this program and to help improve it for others and myself as well. Sure, theres room for technological improvement, but with time and useful feedback I believe these small issues will be resolved.
