this is spec related but I'm posting it here so I won't derail all the great discussions happening in the spec channel.

doing a live demo of spec and a data structure you thought would conform is actually invalid, do you a) ask the audience if they can see what you did wrong? b) call explain on your data structure and see exactly what you did wrong?

@gdeer81: i think it depends on context, time available, whether demo includes learning explain, etc

But in college my fav class involved interactively doing math w the prof

And i think "asking the audience" is great and makes things fun/memorable

I think one way to think of this is have the convo in ur head out loud and bring in explain as ur friend to ask as part of that convo and include the audience in it
