Oh and when they say that less that .05% of documents are affected think of it this way.
Worldwide how many users do you think there are of the free google document stuff, 1 million, 5 million? 10 Million? More?
Lets say each of those people have 50-100 documents. that is between 50 million and one billion documents. That works out to between 25 thousand and half a million documents. A mere pittance!
