I had  a reader point out a minor typo on page 11. I had “your” when I should have had “you’re”. I have updated the page – which if your only reading the comic online doesn’t matter because that page isn’t going to be published for weeks, but if you downloaded the PDF before today your PDF has the typo. You can download the new one with the correction, or who knows? In some far off future digital copies of the ‘bad’ draft would be worth…. nothing extra because its only a digital copy. Oh well. The business model that post offices seemed to have of making extra special valuable stamps by printing versions with mistakes doesn’t really work in the digital world.
