GUYS THE NCAA TOURNAMENT IS IN THREE DAYS. Exciting! And since the tournament has become—I'll say it—our country's biggest and best communal sports experience, even the computer nerds at Facebook have succumbed to the madness. Today, the social network analyzed how many Likes each tourney team has on its fan page, creating maps that can say, conclusively, which schools have the best social media teams are the most popular in the country.

A few key takeaways: 

• The ACC is incredibly popular. Look at the stranglehold it has over the South and East Coast.
• UNC has the most liked fan page, and are far and away the most popular team in the South bracket. Not bad for an eight-seed. (Related: Duke's national popularity may be a bit overstated. North Carolina dominates it in the two schools' head-to-head.)
• Indiana could have a lot of local fans around for its games in Ohio and D.C.
• Just as Gonzaga will be playing in home terrority in Salt Lake City and Los Angeles.
