I agree with you and Tony, what's important is not what tool is used, but what helps the person attain the skills they need to succeed at what they are trying to do. Whether that is a formal training with an instructor or a wiki full of best practices or a short elearning course, the instructional designer/human performance/org development person should be there to help with the success of the operation, not the specific success of the "training department" and formal trainings. If we have to change and adapt to the new world, then that's what we need to do.
