YADIS in one sentence

[Joseph Holsten]

Short version: "Yadis ties services to your Web 2.0 identity"

Long version:
"A Web 2.0 Identity exists on the web. So it must be a URL. If anyone  
knows you by a URL, you've got a web identity. Web 2.0 gives us  
distributed services all around the web. So a Web 2.0 Identity needs  
to be tied into the services you need and use. That is what Yadis does."
