Yes it does!! But more important than the nuts and bolts concepts of how to shift, divide, compute and subtract are the concepts of modularity, documentation, flow, documentation, structure and documentation. Without good architecture the cleverest selection of opcodes and tricky bit fiddling are can lend to just so much more garbage!!

Let me comment that in most cases where I've had to take care of others code I have not changed the coding itself. Almost always it is a case of adding structure and documentation. Sometimes in the process of doing this process latent bugs are uncovered and get corrected. Sometimes an unexpected "feature" is discovered and properly dispositioned.

Personally I have had little feedback from others that my coding is garbage. I have had countless projects where I've supported others that took over my code and gotten a steady confirmation that I did a good job. I also look back sometimes to code I wrote even back as far as the 8080 days (late 70's and early 80's) and I'll marvel at how "nice" it still looks. More than once I've complemented myself as "damn how clever".

I've also seen plenty of excellent code done by others that I just loved looking at and if I knew the author I let them hear some really nice words about the code.
