Well written article, concise, astute and directly to the point. I really like the featured stock image with the smartcash logo emblazoned on the laptop (nice customized touch).
I think the biggest problem regarding the brain wallet is most people have very poor memory and prone to forget passphrases (of course there is a plan B if needed). Most of us can't even remember our own 8 character passwords resulting from we have setup so many different accounts, here and there. However all things considered, I love the idea of the brain wallet forcing us to work on our memory, and it adds yet another interesting dimension to the SmartCash suite of cryptocurrency tools. Two thumbs up! Upvoted! Tweeted! and Resteemed!
