Do you think bridging the gap between generations is a good thing or a bad thing?

Now with this nifty new fangled invention we call the Internet, I bet it is the first time in history that people of all ages mingle freely amongst each other. Here we are on SW, teenagers to retired folks chatting and sharing ideas and opinions.
Does it help us as a society to understand and better communicate with different generations? OR....could this be a potentially dangerous road to go down where the saying, "Age is just a number," will really be true?
