Back from Silicon Valley fundraising. Blogging should resume regularly. For my first post back, here's a second quote on Harrah's from Winner Take All, the casino run by math-types.
When Loveman realized that losers are miserable, he figured he could keep them gambling longer if he could reduce their perception of losing. [...] Harrah's began tracking gamblers' losing streaks in real time while they were still sitting at the slot machine. As soon as a gamlber stuck their Total Rewards frequent gambler card in the machine, the computer started comparing their actual losses and winnings against the predicted odds. Big losers were flagged in the system. A "luck ambassador" was then dispatched to perk them up with friendliness and a token gift.
Arguably, web apps have any real-time usage interaction data that they want. Are there any that use this info in real-time to make users happy?
