Radical Openness

It's the new buzzword:

Yahoo Inc. is swinging the doors of its Web platforms wide open to let outside developers create applications across its network of sites and is radically stitching together its online services under the social profile concept.

The idea is to let the hundreds of millions of people who use its Web mail, instant messaging, calendar, photo management and other online services replicate the social experience that social networks like MySpace and Facebook have made so popular.
