Jeff also owns this domain that redirects to this book:
algorithms.wtf
algorithms.wtf
His illinois.edu page is the second hit for me for "algorithms wtf" in DuckDuckGo and the first hit in Google. There is a non-zero probability that I would find his book by searching for that.
Edit: Sorry if this came across as disrespectful. I don't think that a SEO hack in this case is bad. If you put your care and attention into writing and revising a 472-page textbook, you want people to find it. There's nothing wrong with that.
If I had to pick between say algorithms.me and algorithms.wtf, I'd definitely go with the second one, especially because students like me will remember it for life.
