An important factor to note is that it's rare for anyone to sell a first novel written before they turned 30-35; long-format fiction tends to require a bunch of experience of human life that takes time to acquire. So your average mid-career novelist is in their forties to fifties!

Publishing is the final step in making a book; if I was afraid to publish one, I wouldn't write it in the first place.

I was Computer Shopper's linux columnist for more than half a decade, from the late 90s onwards. Yes, I know about Linux. (My first review of a Linux distro in the press was published in late 1996.)

I was heavily into AD&D in my teens (late 1970s-early 1980s) but fell off the RPG habit in the mid-80s and have never gone back to it; my lifestyle today isn't very compatible with having a regular gaming group (too much travel).

I don't think most of my opinions, political or social, are so far outside of the mainstream that they'd cause massive outrage on a scale liable to provoke death threats or referrals to prosecutors for outraging public decency, so why worry?

Contract law is essentially a defensive scorched-earth battleground where the constant question is, "if my business partner was possessed by a brain-eating monster from beyond spacetime tomorrow, what is the worst thing they could do to me?"

When I do get to chow down on a book, I try to read ones that are nothing like what I'm writing. So, as I'm currently working on a space opera (of sorts) I'm mostly indulging in urban fantasy.
