Business Week writes about a very Web 2.0 thing:
What they’re all seeing is nothing less than the future of the World Wide Web. Suddenly, hordes of volunteer programmers are taking it upon themselves to combine and remix the data and services of unrelated, even competing sites. The result: entirely new offerings they call “mash-ups.” They’re the Web versions of Reese’s (“Hey, you got peanut butter on my chocolate!”) Peanut Butter Cups.
“The Web was originally designed to be mashed up,” says Google Web developer Aaron Boodman, the 27-year-old creator of a program called Greasemonkey that makes it easy to create and use mash-ups. “The technology is finally growing up and making it possible.”
The upshot: People are seizing far more control of what they do online.
