Looks excellent. Note the EDU pricing (or more free). Check out Peter Morville's excellent example using Prezi and learn a little Information Architecture while you're at it.

Great to see Peter Morville drawing the analogy between web architecture and building architecture - I just wish he would put our website on his list of recommended links!
The web architecture/building architecture analogy is better than the information architecture/building architecture analogy for two reasons (1) websites are what we are talking about (2) you do 'build' websites but you do not 'build' information. One day, just possibly perhaps, the University of Greenwich programme may revert to the course title MA Website Architecture. We just have to wait for the rest of the world to catch up with us.
