Re: why, why, why... what is the point?
If you only secure data you want to keep secret, then you are telling the bad guys exactly which data they should concentrate on. If you secure all data, then the bad guys will waste resources trying to decrypt your cat videos or e-mail to your grandmother. Most people won't stop using their debit cards, cell phones, etc to protect their privacy because it is too inconvenient . Using HTTPS when possible is one of the easiest ways to protect your privacy with very little hassle.
