I did end up naming all of my episodes on Tapas. This does two things for me. One, it allows me to instantly recognize the content of each chapter when I want to look something up. Two, it's one more tool I can use to establish an expectation for the reader. If I title a chapter, "Pirate Queen Loses a Bet, Dates the King of Farts" the audience will hopefully clue in that this part isn't serious.
In the case of some projects, like Alien Fiction, the chapters are both named and numbered. The reason for this is that not all episodes are chapters of the story. Some episodes are side features like rules for a roleplaying game or text of a Creative Commons License. Numbering the story sections like "Chapter 3: The Axe" allows the reader to easily skip over parts that do not trigger and interest.
