Yeah, on the spectrum of ways to make money, running a sports betting site is pretty bad. It's zero-sum (unlike, say, founding a company and getting rich from shares that were initially worthless), doesn't really incentivize discovery of any truly valuable info (if you find out a player is injured an hour before everyone else ... ok?), and seems to disproportionately hit people who are already not doing very well.
Seeing the statistics about young American men's betting habits makes me feel old.
