From what I can tell, I'm being downvoted because taw doesn't know what arbitrage means. This is happening on a site called "Less Wrong." The Internet is a fantastic place.

No, you were downvoted for talking about what "[taw is] trying to figure out" and being wrong about it.

You can't arbitrage a single wrong opinion; you need two external differing opinions to start looking at arbitrage opportunities.

If this was your post then I (for one) would have voted you up.

The Internet is a fantastic place.

(Now I am downvoting you Making a False Claim While Under the Influence of Petulance.)
