This article on an Icelandic experiment in “crowdsourcing” its constitution through social media highlights some important distinctions between participatory democracy and government transparency:
Tiago Peixoto, Director of Research at the Electronic Democracy Center at the University of Zurich, and one of the world’s foremost experts on digital participatory governance, tells Fast Company that transparency should be not be confused with democracy.

And even if so, their influence might not be so wise.
