I’ve been highlighting for some time about the need for HTTPS (which encrypts web sessions with SSL) on social websites such as Facebook, Twitter and foursquare. The Firefox Firesheep plugin has had something to do with this change of thinking, so it’s no surprise that Facebook, Twitter and foursquare now offer HTTPS functionality. There are some differences in the way each of these websites delivers HTTPS. One significant difference is not all default to SSL encryption.
Foursquare is the only one out of the three that has rolled out HTTPS as default and it does it with the main website, the mobile website and most important of all the clients. That is some investment I can tell you! 🙂
A major headache with SSL encryption is performance which is why social networks (which have higher than average traffic usage) haven’t taken to implementing HTTPS either as default or as an option. It’s important to note that Twitter and Facebook on the other hand don’t default to HTTPS – users do have the option (and some I know don’t know how they enable this) but hopefully given time these social networks will provide this service as default.
Safe surfing folks!
