Somewhat disappointed. For some reason, the talk does sounds like it was scruff-ed from a couple hours of chatting with a friend. It holds very little information about architectural, design, implementation guidelines specific to JS (except for a few tool examples one can pick up faster with google). No JS-specific examples of how to plan ahead to help programmers improving their log. Not a lot of value besides pointing out the obvious.
Nice effort but too much chit-chat. Very general information. Nothing groundbreaking. If you know that there are log levels like debug, error, warning, and info then you know 95% of this talk.
