First of all, next sportscaster to use the buzz expression "Lin-sanity"  go to your room.    However the story of New York Knicks guard Jeremy Lin is creating a firestorm on social media. Even if you're not an NBA fan, you won't be able to dodge the ubiquitous Lin on Twitter.  Lin's story is quite incredible. One writer wrote, " ten days ago, he couldn't get off the bench, now in New York he's Frank Sinatra."  Simple story, well not exactly. The undrafted player out of Harvard got his chance to play and has averaged over 28.5 pts in four games..and he still lives on his brother's couch at NYU.  The biggest numbers though are via Twitter. The Twitterverse loves Lin...as he has gone from virtually no followers to around 200,000 as of this writing. His Knicks jersey is also the biggest seller this month. Simply Lin-credible!..Sorry.
