I've gotten many hundreds of messages like this since my MOOCs on algorithms launched in 2011.

Hearing stories like this never, ever gets old. 

@has so happy you found it useful!

One unexpected thing about the MOOCs is that it's in some sense the "pursest" teaching that I've ever done --- no certification, no assessment (other than self-assessment), etc. Everyone there was/is hungry for knowledge and skills, in many cases with few other avenues to attain them

I enrolled for your Algorithms specialization many times but found the theory hard to grasp. I'll attempt once more this year💪
