It will most likely will not be a destination. It is there when you need it and gone when you don't.I almost agree with Lee on this, but I do think there will be destination or at least a guide that can be brought up to provide suggestions about learning opportunities, resources, additional content that relates to what you are viewing.
It will track or pull data from many different web services. i.e. your feedreader, flickr, or youtube.I agree that it will be somewhat agnostic about the content that will be considered part of learning, but there will be a big issue about tagging pages and events that are considered part of learning. It won't be sufficient to visit any page about a topic in order to get "credit."
It will not be an HR system.Not sure I get this. It can be driven by HR, learning or a business unit.
It will both generate and store a lot of the meta-data about learning.I completely agree with these comments.
It will allow other systems to integrate workflow, learning content, and social interaction on top of it.
It will foster single user adoption and empower that user within any environment.
Brent raises some interesting questions about what it will look like. He refers to it as a Learning Dashboard. But I believe it can be a destination, i.e., a learning dashboard, but it should also be capable as being a guide as you complete other things. In fact, when you look at the discussion around Web 3.0, part of it is showing what relates to what you are looking at. There's an opportunity to do this based on learning paths within limited context.
