Who uses "sobriquet" instead of "nickname"? Anyone seduced by the assonance you get when you tack the former onto "self-styled," that's who. There's a rhythm to it, too. I like the English language, you know? I want to make it do tricks.
And anyway, "relatively inaccessible" to whom? The folks who read my site or buy my books don't seem to have any problem with the way I write. Don't get me wrong - I'm not slagging anybody who doesn't like the way I write, let alone implying that they're somehow not intelligent enough to get it. But I do know my audience.
I'm not sure this is going anywhere, frankly. Like I say, I'm happy if you got anything at all out of the post, sorry if you didn't, and especially sorry if you feel that post didn't repay the time you invested in reading it. I happen to think it's a pretty neat piece of writing...but then, I would. Others may or may not agree, and that's fine too.
