I've actually thought a bit about this over the years, and wrote a whitepaper in ~2002 on such... (sorry that file evaporated a decade+ ago)
Whereby ;
And this was prior to Cloud BTW (and I met with some goog eng friends in 2006 or so about it, but they said it would never be a thing:
I wanted a cloud based desktop, with your personal encrytped access key being your phone, which you would dock, and then grab an instance of your desktop from the cloud... (a while later motorola tried to launch such a device...)
Anyway, here is my current take:
Every phone should be able to have a way to manage your own APIs such that your links to whatever media buckets you have/sub to - you can very easily just create little widgets that will pull your IGs, HNs, whatever and you can just slide the content-boxes around and organize a page very easily...
Add a content-box (we attempted to build a site around this idea in ~2005 - no bueno - as mobile didnt exist as it does today)
the content box will be [text, pics, audio, links, etc] and you can nest one on top of the other...
So add an element - then drop it on top of another to have the link (think tooltip hover to whatever child box on parent)
etc...
Cloudflare the F out of it - and allow for black/whitelists of content within the profile of the user (never link to FB or Twixxxter, whatever)
You get the gist.;
