Perhaps the entrepreneurs creating the game should be applauded for finding a way to make money out of nothing. Perhaps they should be criticized for building time-sink applications that hoover brainpower and creativity away from more useful pursuits. Either way, no one's ever going to die wishing they'd spent more time on Farmville. We need games, to be sure -- leisure is one of the great gains of human progress. But there's something a little nefarious about games designed only to be addictive time-wasters that create residual revenues for the users. Games can do some remarkable things, though: Researchers found that playing Tetris within 6 hours of a traumatic event can dampen the impact of those disturbing memories. Apparently, the game uses the same portion of the brain that stores those visual and emotional memories and thus erects a barrier to their full impact. This raises some serious ethical questions about how far we should be willing to go to lessen the impact of the unpleasant: It's one thing to offset PTSD, but to what degree will we be interested in "erasing" memories (insofar as we will become able to do so) in the future? To what extent are good and bad memories alike responsible for forming our self-identities?

Ironically, it's also the sale price for which a Russian businessman (and former KGB agent) just bought The Independent, another national paper in the UK. With so many newspapers in such great financial distress, it won't be surprising to find that many of them end up being snapped up at fire-sale prices by individuals with fat wallets and a personal interest in the social prestige that has always been associated with owning a newspaper. Whether those individuals try to apply their influence in good ways or bad will be a matter requiring close scrutiny in the future.
