I don't think the average person is going to get smarter because of the Internet but that possibility exists, doesn't it? In a fewer than 15 years, global connectivity has gone from near public obscurity to being considered boringly familiar.
If one has a desire to broaden one's horizons, then an avenue is available. Today, as a society and individuals we need to learn how to ask more questions. As I was poking around finding resources for yesterday's entry, I discovered new things. I was looking up references to a particular style of Sri Lankan music and found that the Sri Lankan Broadcasting Corporation now streams several feeds. I did not expect to learn that radio was first broadcast in Asia from Colombo. Without access to the Internet I'd never have read of a Mr. Edward Harper, especially as it was a weekend. Information is now not locked in a specific location accessible to a few at specific times. It's easy to find voices from the opposite side of the earth.
