Safari Web Clips vs IE 8 Webslices

Porque é que será que a nova e inovadora feature do IE 8 chamada Webslices que é apresentada da seguinte forma:

Web sites can expose portions of their page as a WebSlice that users can subscribe to and bring that content with them on their links bar wherever they are on the web. Users receive update notifications when the content changes.

… me faz lembrar a feature Webclips do Safari/Dashboard do Leopard?
