It is highly NOT RECOMMENDED to use brainwallets. Humans are a horrendously low source of entropy. There are multiple research papers and programs that show that brainwallets are horribly insecure and easily cracked as what you think is a strong password probably is not a strong password.
And yet if you look here:

https://bitcointalk.org/index.php?topic=885616.0It certainly isn't a simple thing to create an effective brainwallet but it also certainly isn't impossible (as I've demonstrated for four years).
That last sentence is rather important, and usually gets lost in the noise.
It's not a question of whether or not it's theoretically possible to create a safe brain wallet, it's one of whether or not it's a wise idea to promote them.
I've no problem if CIYAM wants to create a brain wallet because he's demonstrated that he generally knows what he's talking about, and is willing to accept the risks.
I've a big problem with OP (or anyone else for that matter) promoting brain wallets in general because of the damage it can cause. This is further compounded by the fact that most people (I'm no exception) tend to overestimate their knowledge of a subject they haven't thoroughly studied ("maybe someone else will choose a bad brain wallet, or forget their brain wallet due to a wetware malfunction, but
surely I'm smart enough to avoid these problems").
In short: please don't use brain wallets. Please don't promote them (that includes you, CIYAM).
