There's been a number of references to AdWords budgets that have effectively been destroyed by todays changes. They're spread across various threads -- so if you're comfortable with restating those numbers again ... let's put them all here in one simple thread so that some intrepid journalist can find a quick and easy reference to tally up. And start writing about.
I'd recommend trying to keep the discussion to a minimum so that the thread doesn't go off track - just sticking to the basics of how many of your keywords have been destroyed, the %age increase you're being expected to pay, and - most importantly - the total amount of money you won't be spending on AdWords now due to the changes. Based on what I've seen so far ... it's in the millions already.
