I think it would be good to add a section on brain wallets, and the importance of good passwords. Bitaddress.org for instance offers Brain Wallets. It has a warning to use a strong password, but I don't think enough people know that passwords like {1summer2leo3phoebe are not strong enough
(source) and can be hacked brute force.
Im really interested in brain wallets if anyone could explain how they work.
