Social networking and online self-paced will merge into social self-paced training. I am convinced of this. After all, online self-paced training is content just like a YouTube video, a picture on flickr, a blog posting, or anything else. It can and should be commented on, rated, and shared.
In my posting on the Is Social Media Making You Think from the ILS blog I talk about how e-learning professionals need to be thinking about how to include social media in their e-learning strategy.
Informal social media doesn't replace formal online self-paced. Social media does significantly improve the learning and retention of online self-paced. This is the future, how do you make it happen?
