I'm interested! I have some exposure to algebraic topology but only through physics so I'd benefit from a formal treatment. I also have formal CS background.
Edit: If we're doing exercises too, a chapter a week is a bit too fast for me since I have other things to do too. I can keep up with that pace through the first few chapters, but eventually I'd hit a point where I need time to think through things carefully. That being said, I don't *need* to also do the exercises, though.
