Among others she talked about:
Facebook (and Facebook apps)
Chicago Crime Statistics
Housing map (from Craigs List)
SuprGlu (and Frickeglu) (seems like a place to have a bunch of your own stuff come)
How do I make one: add this app (point & click...like Facebook, iGoogle); clone (Pipes); program (server side --to do some programming need to request and get a key).
When is it OK to mix? Many have creative commons copyright licenses, but other have limitations (like Google Maps). What is the provenance (the Wikipedia problem)? What is its authority? How simple and what support will you get? Will there be upgrades? What happens with changes in software.
An account for the presentation has been set up:
(password is web2.0)
Another interesting site is mashable.com (inlcudes news related to social networking software), can subscribe to an RSS feed. There is more an more info on mobile computing.
Others are listed on the PowerPoint (which I will try to add as a link). Now the question and answer session is going on, but I am going to post anyway.
