On a related note, I got a pleasent surprise when I opened the Developer Console on Facebook.com: they present you with a giant red warningp[1] and block any code execution in it until you explicitly 'allow [your] account to be hijacked if I paste malicious Javascript'[2]

Facebook blocks the console as it is supposedly used for " exploitation by people to post spam and even used to "hack" accounts"

When you consider Facebook's target audience, it's probably okay to make people like us jump through a hoop in order to stop Grandma from being completely p0wned by typing in some JavaScript.

Yes, maybe people should know that running arbitrary JavaScript is dangerous, but they don't.

I like what MDN does: https://dl.dropboxusercontent.com/u/9161524/Capture2.PNG

BTW, that warning is starting to drive me nuts.
