As the details of EMC's purchase of Dantz were being finalized, the PR teams for both companies were hoping to keep the secret until the moment they had decided to make public announcements. Unfortunately, their plans were leaked in an untimely slashdot article. This premature disclosure could have made a real mess of their PR plan if it weren't for the fact that Guillaume du Gardier, a member of the public relations team in France, was a blogger and had a PubSub subscription to mentions of EMC and Dantz.
