To its credit...
"To its credit, and unlike many of its peers, Twitter gives users the option of surfing the vast majority of the site with the use of the secure sockets layer protocol, a measure that makes it harder for scammers to trick their prey."
It also turns you into a terrorist, though, since Jacqui/Phorm can't see what you're doing, unless they've forced you to use that "man-in-the-middle router" that I saw on comp.risks yesterday. (In the future, all internet traffic will be encrypted by default, but we'll be forced to give the keys to the authorities, who will stick them in the Uberbase, which they then make available to a few million stakeholders.)
