Think I'm looking at this differently - as breaking down the granularity of a page. If you standardised on a card API it wouldn't quite be a web of things but takes you in that direction. Something like RSS/Atom but less general and oriented to individual items rather than lists, with a richer data model. That content is then available to pages and apps equally and could maybe help against the walled garden effect.
