Reactions to the Blackboard acquisition of Wimba and Elluminate. Joshua Kim says this is very smart for Blackboard, but customers should be worried about lock-in. Steve Kolowich surveys Twitter reaction. Barry Dahl says "Blackborg rides again." George Siemens comments (accurately) that the messaging from Blackboard on this is meaningless. Nothing like starting a new product line with a misrepresentation. He nonetheless has a well played compliment to give the company. Matt Crosslin says "the point of education is to collaborate and learn, not just buy everyone."
