In the 2007 comedy "Knocked Up," Paul Rudd's character goes to great lengths to conceal his fantasy sports habit from his wife. Yahoo Sports is hoping that isn't a widespread phenomenon--it's just upped the social quotient in its fantasy football product thanks to its recent acquisition of software company Citizen Sports.
Updates from Yahoo-based fantasy football leagues will be pushed to Facebook for the first time (in addition to Yahoo's own Yahoo Updates), with teams and leagues now "like"-able using Facebook's ubiquitous button. That's pretty much a no-brainer for Yahoo, considering Facebook's dominance in all things involving communication and interaction with other humans online. That said, it doesn't look like there will be any real interaction possible from Facebook's end--like setting lineups or making roster moves, so in the end the Facebook integration is more just to be able to tell your friends.
It's also launched a fantasy football Android app to accompany its existing iPhone app, and has made a handful of previously paid features free (Draft Kit and Dues Tracking among them).
But these updates, specifically the Facebook integration, could have one fairly insalubrious side effect: Filling a Facebook news feed with fantasy football news could make it pretty evident that fantasy sports have way more in common with FarmVille and Pet Society than your average sports fan would want to admit.
