Interesting theme of Smartr and another great iPhone app, Pixable:
Everyone has Facebook now, so the only direction forward is more fragmentation as secondary networks and data stores proliferate.
Stuff like Twitter, Instagram, Dropbox, Gmail/Gplus, iCloud, etc.
But one thing Facebook doesn’t do is aggregation.
So, opportunity: get users by aggregating.
Like Flipboard. Or Smartr or Pixable.
