> Using controlled vocabularies for column names is a low-tech, low-friction approach to building a shared understanding of how each field in a data set is intended to work.

Can't stress how useful this has been working on data science teams. There is really an art for getting a group of people to standardize around a vocabulary of column name pre/suffixes without being overly prescriptive.

Being able to unlock nifty tools / behaviors by naming your columns certain ways seems crazy powerful. (Like a form of function dispatching)
