Twitter & Facebook over Wifi broken - Firesheep

Thought I had better pass this on (until they implement a fix) it's potentially simple for anyone on a Windows laptop or Apple Mac to hack into your Facebook or Twitter account if you are accessing it via public wifi (this has always been true) but now someone has written an application (FireSheep) that lets any idiot do it automatically with a click of the mouse...better not use either of those services in a public place unless you want to risk someone else taking control of your account...

Please pass on the warning...
