Dear Harold, Just found your blog and glad I did! I've had the pleasure of working closely with some of your colleagues at the ITA, and it's always provocative. With regard to your post, one key to unlocking the potential of informal learning is to bring the technology to the place where work is done, ie. for knowledge workers in the desktop applications NOT in the learning portal, learning catalog or LMS. At GlobalEnglish we did this in a humble way a couple of years back and last year our subscribers did 13MM performance support transactions in the workflow. This was unexpected but a pivotal moment for our thinking - we now invest tremendous effort in meeting subscribers (aka learners or users) where they already are, infusing existing workflows (email, documents, CRM) with performance support and embedded expertise. Every customer that has seen this gets the transformational potential, but until they see it, they don't 'get' it. I liken it to the way Google made everyone a 'researcher' overnight. Why not the same for learning and knowledge??? Looking forward to reading your blog regularly, as you are foretelling an exciting future that is unfolding before our eyes!
