Just had this revelation - I'm working on SharePoint documentation - documentation makes more sense when people get familiar with the product. If they are trying to look at the documentation as some literary set of data, then it won't make sense. The documentation has to invite people to not just use the device, but use it effectively. In that respect, I think this idea while great, needs buy-in from developers to really take off. Else, it will end up being just another book of stuff that's rarely useful.
