I think this program is a great learning tool. It would be great to have new "modules" made as more newer technology becomes available - that way we could do just that module and stay updated without becoming overwhelmed.
I have also learned that I should not be afraid of new tools and technology. Unlike the old days when, as a programmer, I learned to be really careful and sure that I want to press the "Enter" key, now experimenting can be fun without worrying about destroying entire databases and files (most of the time! at least on Web 2.0 applications!).
I have also learned about a lot of the new tools out on the web available to me. I am certain that when creative opportunities come my way, both here at work and personally, I will think about what is out there that may either simplify, and/or enhance how I go about doing what I need to do.
Mostly, I learned that this new 2.o technology is not all that difficult to learn to use, and I should not hesitate to get out there and be adventurous!
