Yeah, more or less.

Elsewhere on his site he says that if you can't use spaces in a password, you should use dashes rather than just concatenate letters together: "this-is-fun" as opposed to "thisisfun."  He's quite adamant this is necessary for the security of your password.  Unfortunately, it just isn't so: if I'm running a Markov chainer to generate possible plaintext passwords, what symbol(s) I use as interword marker(s) is(are) completely arbitrary: it doesn't significantly affect the time to generate text.

So, yeah, like I said: I give a big yuk to his methodology.
