Dean Terry has 400 friends on Facebook, but he wants some virtual enemies.
Mr. Terry, who is director of the emerging-media program at the University of Texas at Dallas, says a major flaw of the popular social network is that it's all sunshine and no rain: The service encourages users to press the "like" button, but offers no way to signal which ideas, products, or people they disagree with. And "friend" is about the only kind of connection you can declare.
Real-world relationships are more complicated than that, so social networks should be too, the scholar argues. He's not alone—more than three million people have voted for a "dislike" feature on an online petition on Facebook.
But Mr. Terry has decided to take action, protesting the ethos of Facebook by literally rewiring the service. Or at least, adding the ability to declare "enemies."
"It's social-media blasphemy, in that we're suggesting that you share differences you have with people and share things that you don't like instead of what you do like," he told me last week. "I think social media needs some disruption. It needs its shot of Johnny Rotten."
Here's what he's done. Last month he and a student released a Facebook plug-in called EnemyGraph, which users can install free and name their enemies, which then show up in their profiles. "We're using 'enemy' in the same loose way that Facebook uses 'friends,'" Mr. Terry explained. "It really just means something you have an issue with."
The scholar would have preferred to use "dislike," but the word is literally banned by the service to prevent developers from creating a dislike button. Critics of Facebook say the social network's leaders want to keep the service friendly to advertisers who might object to users publicly scorning their products...
