At TechStars investor and demo day Tuesday, Tom Keller, CEO of IntenseDebate, went on stage and told the audience that he didn't have any slides, nor was he looking for money. But he did say he had a surprise for everyone. That surprise was Automattic CEO Toni Schneider. Automattic runs the Web blogging service WordPress. On stage, Toni and Tom announced that Automattic acquired IntenseDebate for an undisclosed amount. I heard IntenseDebate raised about $300,000.
