There may be a little irony in the fact that training and development professionals have taken so long to progress along the Web 2.0 learning curve. Even as other experts look beyond these technologies to the next stage, most learning professionals are still trying to catch up. It could be that some simply think it's too late to get on board. Perhaps they have been burned by technology fads in the past and figure that by the time they adopt Web 2.0 technologies, the tools will have gone the way of the abacus and the slide rule.
