It was a pleasure to read your "Glass Half Full" assessment of technology. All too often - as I watch parents ignore their kids at the playground while checking Facebook on their IPhone for the 20th time that hour .... or having 140 character "tweets" replace relaxing face-to-face conversations over a cup of coffee - I tend to look askance at the next social technological marvel.
Probably the same way that my grandparents looked at TV, or my parents looked at video games. :-)
