And thus employment of CS graduates should be compared with employment of Engineering graduates, except in the case of Academia, where it ought to be compared with other sciences.
So he's wrong. People in google should have worked that out, made a point of pointing it out to others, and got on with their work. Instead they freaked out, leaked to the media, and got this guy fired.
How can you beat a linguistic analysis? If you publish elsewhere and someone guesses to compare your work, are you screwed? Are there any programs that scan writing to determine if the writer's english is Canadian or American or British etc? Or maybe your gender? Could you use that to weed out any regional phrases, or use regional phrases from other places to confuse the text? How do you make sure you don't sound the same in your real life, using similar phrases (For example, if Scott Alexander from Slate Star Codex had another blog that was not anonymous, would it be nessecary to not use expressions like 'Steelman' or refer to effective altruism?
Should you look in the academic literature about language, and try to make it so your style can't be detected by theoretical methods of linguistic analysis that haven't yet been implimented computationally?
How do you deal with private communication? Does it make sense to simply have no possible way of privately emailing you, making all communication public (thus giving you plausible deniability if you click any links phishing for your identity). Should you not even interact with public comments?
What about any information you might giveaway even when you are being a VPN or something (browser info? Some kind of computer associated seriel number? internet cookies?). Is it overkill to simply have one device dedicated to researching/blogging, and restricting yourself from doing normal day to day work on that computer? What about a virtual machine?
Can you buy and pay for a domain anonymously?
Should you make a list of things you are willing to reveal about yourself, and stick to it? For example, A/S/L and then make sure never to reveal other details (former locations, trips with dates, schooling, etc) Should you change details of anecdotes if you share them?
If you trust someone, perhaps a girlfriend, or wife, or really good friend, is it too risky to share with them your identity, even if you agree to never discuss any of it digitally? Assuming they also keep a wall between themselves and that identity (not sharing posts, not telling friends, etc) is that safe? If you do break up, should you create a new blog, and if so, is it worth it to make the writing style clearly different from the old blog? Are there any high profile, clearly psuedonymous people who have remained so for long periods of time?
By making this post, should I now do none of these things?
Corporatiosn are dictatorships without freedom of speech. In the case of Academics what you say is true. But not really in the case of Google employees.
