Email Encryption

Today I am at home with commitments. But find myself pondering the pros and cons of email encryption for regular users. It seems absurd that mainstream services were ever unencrypted. But I guess it's harder to use secure services, and the old adage of email being more like a postcard than a letter makes a lot of sense (even James Blunt wrote a song about it - yay go James). For me it's not about The Man - more like the little weasley people at my ISP and in the van outside Starbucks.

Edit: As if proof were needed that I repeat myself.
