I think the Internet is cool for the following reasons:
I can find things I didn't know I was looking for.
I have saved a lot of time.
I have even saved some money (thank you www.paperbackswap.com).
I have connected with people I would not otherwise have met.
My communities of interest have all expanded. Many exponentially.
Here are two things I like. The Media Venture Collective and BooksWeLike. Check 'em out.
