Use Twitter? Want to use HTTPS where possible, to prevent accessing it over plain HTTP, and getting “tweetjacked” by FireSheep users? Twitter now allows you to use HTTPS wherever possible. A good start. Its accessible in your account settings.
Use Facebook? Want to use HTTPS where possible? Account -> Account Settings and look at Account Security. Again, you can enable HTTPS. Very cool.
I don’t know how I missed this, but I encourage everyone to enable HTTPS, especially since I see the most common website at cafes, restaurants and other public places that are being accessed tend to be Facebook. I was at the KL Facebook Developer Garage (KLFB) at the end of February 2011, and I saw two speakers get fake updates on their Twitter & Facebook profiles, so I’m guessing this is not very well publicized.
Go, spend a minute, and enable HTTPS.
