The white paper (http://senseable.mit.edu/urbanvillages/img/manuscript.pdf) gives the assumptions to explain why call data is representative:
"Mobile phone communication data are not necessarily a direct representation of the underlying social network. For instance, two individuals may maintain a strong tie through face-to-face interactions or other means of communication, without relying on regular phone calls [23]. Nevertheless, despite such a po- tential bias, a recent comparison with a questionnaire-based survey has shown that mobile phone communication data are, in general, a reliable proxy for the strength of individual- based social interactions [25]. Moreover, even if two subscribers maintain a close relationship and usually communicate via other means, it seems reasonable to assume that both individ- uals have called each other at least once during the relatively long observation period of 15 months, thus reducing the chance of missing such relationships in our network [21, 26, 27]"

I'm pretty new to HN and am not sure why the post was killed. I was looking forward to an interesting debate on the value of browsers vs native apps. Can you please give advice for how to avoid being flagged while stimulating interesting debate? Thank you for the help.

What We Do TL;DR — Technology Consultancy
The Hackerati is a high-end, boutique consulting firm delivering Engineering as a Service to diverse clients, from Fortune 250s to startups.
Why You Should Join Us TL;DR — We're not afraid to be our wild selves.
We’re different. With mottos like be fearless and weird is good, our unique perspectives on life and technology make us great people to learn from and work/party with. We sponsor lunches and happy hours, band practice, electronics like Glass/Oculus/Myo, and we’ve presented at the UN—twice. We rock that familial vibe, and you should join us if you enjoy a blurred line between work and play.
What To Expect TL;DR — Deliver the industry's most challenging projects.
Hackerati consultants are like The Wolf from Pulp Fiction: we solve problems. Hard ones. To do so, we deploy teams of Hackerati to work onsite with clients around NYC, and also build products in-house, both for ourselves and clients. A typical project lasts between 6 and 9 months—say goodbye to getting stuck doing the same shit!
