In summary, I would say my favorite was Google Docs. I had seen this concept used by my Daughter in her job and it speeded up document development tremendously.
In regard to the 7 habits:
I set a goal to finish--and I did
I accepted responsibility for my own learning but I needed a lot of help from other reference staff.
I have always enjoyed problem solving--this was no exception.
My confidence has been bolstered by these exercises; I actually got better as we progressed.
I think that's enough about the 7 habits.
My one suggestion would be to provide more basic instructions about how to navigate some of the more complex web sites. I spent too much time sometimes trying to figure out how to proceed.
I would suggest that we explore more Web 2.0 in our next exercises. I found this development so informative and I'm eager to learn more

I was somewhat familiar with NetLibrary since I work with AV at my library. The directions for downloading eAudiobooks is clearly presented--explains about license granting, and what portable devices can be used in transfer--well, more like which devices are not compatible such as IPods and Zunes.
A title I might want to try out is "Last Child In The Woods" regarding children and the environment.

I went to podcastpickle as Jammin Dave suggested. I liked their format because I could select an area of interest immediately. Podcastalley was a little harder to navigate.

Interesting podcasts for me would be health, management, literature, and AV discussions.

I had trouble finding a video on youtube that I really wanted to watch. Nothing that I saw interested me, but I finally decided on "Where is Kurdistan?"
The only thing I enjoyed about it was the music--Bolero by Ravel--one of my favorite classical pieces. Also, it was a quick geography lesson in that it circled the globe in search of Kurdistan.

I can see youtube of value in libraries to advertise a program or services--presented on the lighter side.

The Wed 2.0 award winner that I explored was PeerTrainer. It is a health and fitness site. I liked the fact that info on a large variety of diets was available, plus calorie counters, plus exercise instructions, plus group support if you chose to have dialogue with others. There was something for everyone interested in health! The one feature I didn't like was advertisement for products. I could recommend it to patrons interested in losing weight and wanting a support group.

Google Docs could be helpful for library staff in building a program across the region.. It can be a boost for students working on a joint project. Even if a student is working on a research project alone, he or she can add data from many locales. Patrons, too, will find this useful as they work on a project.

Adding to wiki's pages was fairly easy for me. Only problem I had was where to add my favorite-- at the top or bottom. It's fun after you get started!
