As I am confident we will see informal learning become more prevalent in the corporate environment, companies must also be cautious when jumping into the social media and informal learning stampede. There are many social media tools and approaches. Be strategic when identifying social media tools, how they will be implemented, and how you can facilitate learning within the media. Remember, you cannot truly manage informal learning, but you can facilitate learning along with coaching others to facilitate learning. You can also coach learners on how to effectively use social media to meet the learning objectives they set for themselves.
Here are some great resources on informal learning that help us understand this transition from the formal to informal.
First off, Jay Cross and Clark Quinn on how meta-learning subverts the traditional training hierarchy.
Jane Hart's "From e-Learning to Social Learning."
Plus, last November the Learning Circuits blog's Big Question was "Presenting the Value of Social Media for Learning," which had many valuable comments and advice for anyone implementing social media in the workplace.
I think this democratization of learning will be a benefit to corporate staff and if engaged by corporate training departments it will be boon to their ability to assist learners in acquiring the knowledge and skills necessary for their success.
