Frictionless sharing: here to stay?

At the F8 developers conference in 2011 Facebook founder Mark Zuckerberg announced that Facebook would launch new services that allow "real-time serendipity in a friction-less environment". One of the first frictionless Facebook apps was the Guardian's, but over the past few months over 50 others were added.
Frictionless sharing is now used to describe apps that "bring life to your Timeline" to express who you are: a runner (e.g. RunKeeper), a foodie (e.g. Foodspotting), a traveler (e.g. TripAdvisor), a music fan (e.g. Spotify), a movie buff (e.g. Rotten Tomatoes) and more.

From Quantifying Future Trends In Online Sharing, a study released by digital agency Beyond Social Media Week:

Frictionless sharing is here to stay, but it will need to get much, much better. Ultimately, just about everything we do in a day will have the capacity to be shared online, but with accuracy and without needing to activly think about it.
