It's been really wonderful serving as featured author these past few weeks, and I wanted to conclude just by thanking all of the people who made this possible. First, a huge thank you to Thomas Nadelhoffer for creating this whole amazing series. Then, many thanks to all the people who pitched in with comments or questions. I really learned a huge amount from discussing these issues with you, and I'm sure my subsequent work will be shaped in all sorts of ways by your input.
Finally, I am incredibly grateful to all of the extraordinary coauthors who worked with me on the papers discussed here. They really drove this research and provided most of the important ideas at the hearts of the papers. I thought it might be helpful to wrap up just by listing them all.
