Catching Up: Why a .338 Hitter is Better than a .833 Hitter, etc.

I'm emptying out my linkbox with a few things other people may find worth reading:
  • Fascinating stuff on why a .338 hitter in baseball is better than a .833 hitter. And, more importantly, why a .334 batting average is the best predictor of actual average. (ASA)
  • D.E. Shaw refuses to stay in the hedge fund box, and is now doing everything from computational chemistry to solar power (NYT/DE Shaw)
  • Wikipedia has a good entry on the whole "Does 0.999... = 1?"
    issue. This, for reasons too obscure to mention, took up a bunch of my
    time in a semi-debate with someone yesterday. (Wikipedia)
  • Nick Wilson is Twitter-ing a live birth (Twitter)
  • Fascinating data on Twitter vs Blogger growth (Kotke)

Wow, I've been thinking about that same math 0.99... = 1 convention within the last couple of months (I think I can explain why it's wrong and that it's more of a philosophical debate). Can you summarize why this was an issue of contention for you recently and which side you come out on in this endless debate? I'd be interested to hear about it.

Could someone please explain the batting average thing to me in plain English? Thanks.
