Erik Ringmar is someone with first-hand experience of the issue of free-speech vs censorship in the on-line world. While anyone who is interested in these issues can theorise about the impact of censorship it is interesting to hear from someone who speaks honestly and openly about its practical effects (he was diciplined by the London School of Economics when he was a lecturer there in part because of things he said about the LSE in his personal blog).
Ringmar admits that his way of going about things is not always the best way or even the right way, he is quirky and that is his charm, however the lessons that he has learned and powerfully states are real and forcefully told. This really is a manifesto for free speech anywhere told by someone who knows what it really means.
