Social networking and learning?

Over the past year or two the social networking phenomena has built at an incredible pace. Some businesses are beginning to see its potential whilst others see it as another way for lazy employees to avoid getting down to real work. What most commentators seem to agree on is that the ‘young’ are the real masters of social networking and will be the ones who bring it fully into the mainstream as they enter work.
I came across this article the other day that gives an insight to how social networking is entering the mainstream of business life. It will be interesting to see how it starts to impact on learning.
