Good and enlightening post. I particularly like the part where you talked about the importance of strong passwords. It's funny what people use as passwords, some are very brief and easy to arrive at, some are quite easy to forget, some are inconsistent with their use of passwords, they use different passwords for each account they have and this isn't advisable. In all the best way of choosing a password I'd say is through the use of alphanumerics and also staying consistent.
