MOOCS can be useful and I'm not saying they're bad. OP was asking if they're very useful for signaling. Imo compared to projects from professional work or open source with traction; or even traditional education - most MOOCS aren't very good for signalling. The only exception I can think of is special classes like those involving building autonomous cars.
