Harold,

I'm sorry to hear that it sounds like you have left LearnNB. Open source with regard to learning faces a lot of resistence especially in the enterprise market if only because of the prior investments in buying commercial solutions. Likewise informal learning struggles from the reality that not everyone is equal when it comes to sharing their knowledge as the quality varies. Here at Thomson NETg we use open source in our solutions but then build a picket fence around our users to make sure that they are authenticated before accessing the content and collaboration options. It makes the buyer happy (the company re security/accountability) and the user happy (validated or refeered content/collaboration).

Somewhere I hope a happy medium will appear that reduces the cost of investing in learning while ensuring that those that build effective learning solutions can profit from it. If anything, the small market today for eLearning creates expensive solutions as you basically only have 2 levers to play with - price per 'unit' and the number of 'units' sold.

Wikipedia just forked and is looking to create a moderated version called Citizendium. Something to think about?
