Wiki training

I lead my first wiki training session tomorrow morning, and the PPT slides are ready. Thankfully my maiden training voyage is with people I know, so nerves won't be much of an issue.

As I worked on the training, I realized just how important it is to our long-term success. In a previous life working on IT projects, it was the case (more often than not) that training was an afterthought -- and it showed! (Don't get me started on the anemic documentation I used to see, which thankfully is not an issue with the wiki.)

Training is so important. What's the use of giving someone a Mercedes if they park it in the garage and only use the CD player?

How do you do wiki training, or training for social media in general?
