Scott Leslie has collated a variety of PLE diagrams. Sure to come in useful for presentations, roadmap plotting and just plain old inspiration.

Made me actually think about what my PLE looks like? Lets see:

1. Google
2. Del.icio.us
3. Facebook
4. Firefox
5. Backpack

It must be a good day - I have after all encountered two EDU 2.0 apps. Cohere, from Open Uni UK, takes concept/idea mapping to a new collaborative level. Add ideas, make connections and then discover related ideas and people.

Research paper on Cohere: Towards Web 2.0 Argumentation.

Webducates’ Dragster fits the bill as a EDU 2.0 app. Check out this example activity where users can not only classify existing topics but add new ones as well. The emphasis here is on the fact that this activity can be completed by multiple users asynchronously.
