Not yet, I'm sure they are out there! But I'm guessing they are busy doing more useful things than giving these kind of demos πŸ˜„

Ooooh, I made a tool that can extract a dataset from the activity data (issues/pull requests) of a GirHub repo. I'll try it with the tidytuesday repo next week to see what comes out πŸ˜„
