   Format: MarkdownItexQuestion about an obvious typo with no obvious solution: In the proof of proposition A.3.1.8 of HTT, we factor a weak equivalence $f:K\to K'$ as "$K\to K\times K'' \to K$, where the map $K\to K''$ is a cofibration and $K''$ is a contractible Kan complex. Clearly, there is an error here, but I'm not sure where the apostrophe ( ' ) is supposed to go. On just the final K, or also on the K in the product? (By the way, guys, sorry for asking questions like this here. I have nobody else to ask, and the appendix has at least 100 (if not more) typos).

Maybe not on each and every question somebody finds the time to look at the question, understand it, understand the reply, and then give the reply, but asking doesn't hurt. That's what a discussion forum is about. > I have nobody else to ask, and the appendix has at least 100 (if not more) typos So have you started typing an errata-list somewhere?
