Informative post by Seth. But why would Google Docs be any more trustworthy than Google search and other freebies by the Gorgon? With the admitted cooperation of Google with authorities by law and by commercial opportunity? Same dubity applies to cloud servers whose biggest most lucrative customers are governments and those most eager to gain government favor. The seemingly endless pursuit of the holy grail of online security, yet remain within government protection, is daunting if Sisyphean: the Soviet-style collectivization of hiding, exposing and faking vulnerabilities and illusory defenses; Guevara insurgencies of work-arounds, Cheney-like enforcing of fire rediscovery and wheel reinvention; David Blaine levitation of wizard coding reputations to cover deliberate back-dooring for personal gain and patriotism; TLA-grade proliferating outlets for inseminating infected blood into coding with rigged modules under cover of malware combat aka as freedom fighting for chauvinistic-tainted comsec validation as diseased as Crypto AG. It was for a brief period security-wise to reject any major enterprise as a means to protect communications due to certainty those will be compromised by commercial interest and state protection. Now the bigger the better, the more venal the more desirable. Never mind the obvious trickle down from accumulated wealth to needy researchers ready to wear whatever hats fit ambition, personal debt, family obligations, withering of courage, no apologies for changing camps offered.
