Which MOOCs that you have taken till 2022 delivered tangible outcomes?

MOOCs don't necessarily mean courses that are offered as MOOCs. It can be some online course from a public webpage that the instructor of the course just put up for whoever finds it.

Tangible outcome need not be job or money related. It may be related to intense intellectual satisfaction or enlightenment.

If you could say a line or two about the courses add that too.
