[liberationtech] My CPJ blog: Lessons from the Cryptocat debate

Nadim Kobeissi nadim at nadim.cc

I can't even-

Frank sent me this article about 15 minutes ago and I answered with the
notion that Cryptocat has been a browser-plugin only app for more than a
month, and that his article is just incredibly ignorant and frustrating
as a result of it ignoring that.

Excuse me while I now go waterboard myself,
NK
