"Protesters became more careful about communicating information privately after they realised police knew where they were, tracking public posts on social media. 'We were giving out information to police without realising,' Damla said.
After that, links and groups visible only to each other became the way they communicated their location or movements, though they were happy to denounce Erdogan's government and upload photos of alleged police brutality on Twitter or Tumblr.
The use of Virtual Private Networks (VPNs), which hide a user's location and allow them to view the internet undetected, has also seen a sharp increase in recent days.
One app, Hotspot Shield, jumped into the Apple App Store's top five in Turkey yesterday, a rise of 120,000 new users in a week, as the population seeks to keep mobile communications channels open in anticipation of further crackdowns and arrests"

This is a great explanation of how protesters are using the net.  Useful reading for the future.
