An interesting Macintosh application is QuickSilver. I've only used it to launch applications from the Finder but after reading its Wikipedia entry I think I might try some of its other features.

I did a Google search unique presentation styles of Dick Hardt and Lawrence Lessig to look for some more stuff on their presentations and came across one small voice and the discuss of "web of trust". I knew about the web of trust but I didn't know about CAcert the open-access certification authority. I'm thinking about joining. On the about page "CAcert Inc. is a non-profit association, incorporated in New South Wales Australia."! Trust increasing!

Open-access educational content: First Stanford, then MIT, now Yale. Also interesting is "The William and Flora Hewlett Foundation". Hewlett was the H in H.P. From the foundation you can find publications such as Web 2.0 and New Wave of Innovation for Teaching and Learning and Story Thread Analysis: Storied Lives in an Online Community of Practice

At my institution I have to fill a form if I want to even speak in public in case the institution's IP leaks.
