I disagree with his "First Letters from a Phrase" point. I find mnemonic passwords very useful and keeps me from having to open up KeePass every time I want to log in to a system because I can't remember the random password.
I agree that longer passwords are better, which is why I use very long phrases to generate my mnemonic passwords (typically 20-26 characters in length).
I find "first letters from a phrase" harder to type than the phrase itself, because it doesn't behave like the rest of the typing I do. Given that it also has less entropy (necessarily, because of collisions), why not just type the whole phrase?
