Great idea. As others have said writing style, grammer, punctuation are the biggest threat to anonymity.
As a tangent I wonder if there's some sort of lossy compression you could do with English that would mangle this enough to make text anonymous. People have suggest google translate a few times, that's using a translation tool to hide some of the original meaning. Has anyone done a dedicated library to mangle text this way?
what if a site like this integrated a system that identified an individual's writing patterns and alerted the person to them, prompting changes in text they submit, thus attempting to ensure anonymity?
