Please don't use words like "horribly" or "probably" trying to discuss technical issues.

Why? I understand not using probably (I thought this was in beginners and help so it was primarily as a warning to noobs) but what is wrong with "horribly insecure"?

Because how can anyone objectively disagree (or agree) with a complexity of a technical challenge described by such words?

Do you even understand that cracking a brain-wallet's seed password is a serious technical challenge?

Which tool/approach would you have chosen to crack my brain wallet?

It is possible to securely use brainwallets, but it should not be something that is recommended to newbies and those who do not understand technical aspects of Bitcoin IMO.

Which is exactly why guides like this can be very useful.
Unlike dogmatic statements based on someone's beliefs, basically coming down to: don't use a brain wallet, because you are too stupid to make a proper password.
IMHO, there is nothing more stupid (or arrogant) than assuming that all the other people are stupid, except greg and theymos

A brainwallet refers to the concept of storing Bitcoins in one's own mind by memorizing a mnemonic recovery seed
I just find out of this kind of wallet, looks interesting. Need to learn about it later.
Yes, it's so hard to cracking brain wallet as the seed is memorized by the owner.
But, you still have to write it down, right? Just in case, because > If a brainwallet is forgotten or the person dies or is permanently incapacitated, the Bitcoins are lost forever.
