Good video! I always comment on code I write, because if I don't look at it for, say a year, it'll take time for me to see what's going on in my own code if the comments weren't there. Some programmers do nothing but maintenance on existing code. It' programmers' hell. :)
exactly :) Worst feeling when you're swearing about the quality of the code and missing comments..and then you realize it was you who's written it :DD
