Hi Library Lady,
Thank you for your email and reminding me that I have not really responded directly to the question about how I would rate my knowledge about Web 2.0 and its applications. Well, I think that I am about a "5". I am hoping that by going through this course for a second time, I can raise it to at least an "8". The problem is that I do not use it enough to be fully knowledgeable about all of its possibilities. I am hoping that by appreciating its potential, I can use it more meaningfully.
