What an odd thread.
First, if I recall, the proper way to indicate authorship when it's someone else, and you are republishing is to use the rel=publisher. Again, if I recall, Google is fine with this kind of attribution, but clearly the rel=author tag is not a good fit, in most of these situations.
As regarding boosting author profile, I guess this is part of marketing, but I have better things to do than spend my time doing that. Many people would rather create, or help, or do other things that bring more satisfaction. I USE the author profile tag. I think it's a good thing. But I'm not hanging around Google+ just to "establish myself". If that's what it takes to be an authority, not interested. I'm already a real world authority.
As a successful book author in the "real" world, I'll tell you that if I went to my publisher and said I wanted my next book to be published under a different name (without a good reason), they'd go nuts. Branding is critical in book sales.
On anonymity in Google. Ok. Personally, I have very little desire to interact with, or read material authored by "goombaboy". I don't give credibility to people who don't identify themselves, until they have a strong record, as is the case with a lot of vet posters here, but I understand situations where one is concerned about safety. Hey, up to you.
