BOSTON HERALD--Is the computer replacing the kegger on college campuses? "I guess we've all been reared on the Internet,'' said Mandeep Singh, 21, a biology major at the Massachusetts Institute of Technology and co-founder of Matchup.mit.edu, a Boston-based, college dating Web site. Using the Internet to meet people is just another progression for us.'' Two years ago, two Wesleyan University sophomores launched WesMatch.com. Now the duo is expanding beyond their Connecticut campus to dozens of colleges with CampusMatch. There's also CampusFlirts.com, CollegeLuv.com and Matchmaker.com/college connection. And the competition can get heated, as shown by two Harvard-based dating sites. The founders of www.connectU.com are suing the creators of the very popular www.thefacebook.com, claiming one of its founders ripped off their idea.
