I like Diigo because it makes collaborating easier.  The tools were easy to use and they worked well.  I originally didn't like how we had to download an extension in order to use the program.  However, it didn't take long and was easy to figure out.

I like blogging and it wasn't too difficult to figure out.  I can definitely see myself continuing to use it when I am a teacher.  It is a good tool for easily communicating information to a larger audience.

A web 2.0 tool can be used to reinforce a concept taught in class.  I want to use YouTube when I am a teacher.  Some of my teachers used YouTube in high school and I would watch the videos that we saw in class in order to help me study for exams.  I found YouTube to be really helpful because it allowed me to study just by listening and I could use the app anywhere.  YouTube is really easy to use and it's pretty simple to find videos about any subject or topic.  However, I will make sure that I watch the videos before I show them in class.
