Things 18, 19-- Slideshare has the possibility of being a source for subject matter or comparison of different art techniques, although much of what I saw were novelties like car body paint jobs and amateur artists. It will take a lot of culling to find appropriate slide shows of art subjects-- I ran across many inappropriate art works. I know most of our students navigate on Google Earth and I have frequently been shown places by students, but I've never done it myself. This is another thing I want to be taught by a student. I like to set the example of a life-long student and give kids an opportunity to demonstrate their knowledge to an adult.
Thing 20-- Ning is not my thing! I'm an introvert and all this networking is way too social for me. However, I have to say, I do like Skype. So far I have only contacted family and friends, but it would be great to have the visual to show a sick student at home how to do their art project.

I hope we'll have access to the Web 2.0 sites in future years so we can continue to find worthy stuff to try out. I've appreciated the support you all have given and I have had a minimum of frustration in the learning, so far.
