Flip the order of the first two exercises in Live Coding is a Skill

### How could the content be improved?

This episode has the learners think about the Pros and Cons of participatory live coding, and then watch the two videos of Lex demonstrating the practice. In the last two events I taught, about half the class had no prior Carpentries experience, and therefore no experience of participatory live coding. So, I've switched the order of these two in order to give everyone a taste of living coding before having to respond to the pros and cons. This has worked out very well, and I think would be a good change to the lesson.

### Which part of the content does your suggestion apply to?

Start with the linked instructor/17-live.html lesson and locate the first two exercises in the “Live Coding is a Skill” episode. Review their current order, switch the two exercises, and confirm the lesson presents learners with the live-coding demonstrations before asking them to consider the pros and cons.
