Hi Dan! Just catching up on things post-Christmas and came to your reply. I’m glad to hear the ‘three languages’ model helps clarify some things about your role. If you’re in a position where you know the codes of the upward language in a particular area, it’s likely that you can be a lot of help to people who are doing good work but don’t know how to build those interfaces. Anyway, hope these thoughts continued to slosh around usefully — and that your 2017 is off to a good start!
