1. Stone is the one that "feels" the strongest
2. Therefore a novice will expect their opponent to go for stone, and will go for paper to beat stone
3. Therefore go for scissors first
I think my initial choice is rather random, but from now on I may keep their advice in mind.
Another interesting article I've read over the past few days is "On the Survival of Rats in the Slush Pile" by Michael Allen (also known as the Grumpy Old Bookman). It's a little monograph - almost a screed - on the publishing industry and what's wrong with it. Basically, the methods publishers use to determine the value of a book are completely wrong, and the machinery behind publishing is badly broken, and if you want to become a writer and earn fame and fortune, like Dan Brown or J.K. Rowling, you might as well give up now. He also suggests methods for reforming the industry, and his basic advice to would-be writers is: go ahead and write, but don't give up the day job.
It's a very quick, informative read. I especially liked how he threw in some insights from statistics, in particular Nassim Taleb's books about chance as well as the theory of the Long Tail.
I wish more books were like that - short and to the point. What happened to the old practice of writing monographs rather than books? I see so many books in the bookshops these days that talk about interesting subjects, but - honestly, who wants to read 200+ pages about, say, Daylight Savings Time? Or salt? Can't it be compressed down a bit? And made cheaper? Then I could spend less time finding out more, with less pressure on my wallet.
Writers wouldn't have to spend so much time fluffing out their books, either - they could just state their piece and be done with it, sell it for less but probably have more readers to make up for it. We need to make <100-page books fashionable again. They would be perfect to distribute electronically, too. "On the survival..." is 70 pages long, and doesn't hurt the eyes. I couldn't imagine reading 200+ pages at a stretch at the computer. But 70 pages, with generous margins, is pretty good, with a few minutes' break at the halfway mark.
