Live bug squash is better, imo. I was part of the production support at my $DAYJOB. My work was literally finding and squashing bugs all day. And yet, if you were to ask me for interesting stories, I won't be able to tell you anything. Maybe I'll remember the latest bug I solved but most of the time, once the bug is resolved, its off my mind. I will have to go through my jira and github history to first see which bugs I even worked on, then filter for the interesting ones and then try to remember the story instead of just the root cause.
