Sometimes we suck. We think we're adding useful features but we're also breaking people.
It looks like Geek Grrl triggered the Firefox (Gecko) Midas editing mode which is used for things like Blogger.com's HTML editing features. How she triggered it, and why it's available on Google, I'm not sure. I suspect it's a bug in our code that allowed some other page to trigger it and have it carry over to the next page she visits or something crazy like that. (Surely we don't have a keyboard command to invoke it arbitrarily!?)
This feature, the HTML editing capability, is a feature, but users unexpectedly finding Google.com or any other normal site as editable is surely a bug. (Mabe bug 198155 or bug 209836? maybe those reports are the same problem?)
