One small checkbox for your mouse pointer, one giant leap for your Twitter account's security. The microblogging site that every techie knows, loves, and occasionally loathes, has added a new option to allow users to go HTTPS full-time. For the unenlightened among you, that means all your communications with Twitter can now be done over an SSL-encrypted channel, which massively boosts their resilience to external attacks. That won't protect you if you're careless with your password or leave your account logged in on computers other than your own, but at least you can sleep a little more restfully knowing that nobody other than yourself will be embarrassing you on the Twittersphere.
