Should AOL be allowed to release this information? Because this is so early, it could still be just a very big mistake. That is no consolation to those who feel violated, of course.
Update: AOL has apologized today for releasing this information publicly, it was a mistake they said:
"This was a screw-up, and we're angry and upset about it. It was an innocent enough attempt to reach out to the academic community with new research tools, but it was obviously not appropriately vetted, and if it had been, it would have been stopped in an instant."
