Of course all those squares from the Ivy League would use the Internet to find one another. thesquare.com (doing business as TheSquare Network) is an online network for alumni and students of about 100 top-ranked colleges and universities. Subscribers also use the service to find jobs, dates, and classified listings. (The company also operates SquareJobs.com and SquareDating.com.) Founded in 1997 by James Marciano (Dartmouth '93, Harvard '98), TheSquare was acquired in 2001 by Bennett Carroccio (Columbia '85), who serves as chairman and president.
