John Abell takes a close look at Taptu, and likes the flow:

Taptu sticks with some familiar (dare I say boring) metaphors and UI conventions, like vertical scrolling thumbnails. And the basic ingredients of your stone soup are also the same, like the ability to import from your Google Reader, pick from “featured” feeds and browse pre-curated topics.

But Taptu’s secret sauce lets you mash up “mixed streams.” Rather than serve up every feed as a single, walled-off source, you can combine them with each other, websites and searches ad infinitum into what then becomes a single feed. On the web, this isn’t new — Google Reader lets you create “folders” — but in the cramped environment of a tablet screen this is a boon. Taptu even says mixed streams are de-duped — if the same item appears more than once, it’s because it shows up in more than one of your sources, it shows up in your feed only once.

Then, you can share your own dynamic publication with the Taptu universe, and on the internet, even with people who don’t use the app — a nifty and fearless nod to the blurred line that should exist between the closed world of apps and the open and limitless web.
