"Skin in the game" and "arbitrage" are mutually exclusive, and the title of the post is "Arbitrage of Prediction Markets."

It is probably not the best title. Intrade do not try to discourage the kind of thing taw is talking about.

It doesn't strike me as very sporting to edit a post to make it sound like I didn't address your point.

My reply to what used to be here was one of clear agreement with you and I marked the edit explicitly.

For the record, the edit was a remove "No, taw is trying to figure out a different kind of arbitrage". A more correct statement would perhaps be "No, taw is trying to figure out a different kind of thing than what you are talking about and which isn't really arbitrage at all". But that is a distraction from the gist of your post, which I disagree with for the reason stated.

I will, of course, take more care to acknowledge contributions by name when I add edit notes. I erred too far on the side of brevity here.
