The proliferation of blogs and Web sites dedicated to goodness is still modest, but notable, given the stupefying misanthropy on the Internet.
"I do think it's a big trend," says Alyssa Wright, who launched heroreports.org in June. Wright, 30, was working on her master's degree at the Center for Future Civic Media at the Massachusetts Institute of Technology when she dreamed up the Web site where New Yorkers could post anecdotes about acts of generosity or thoughtfulness.
"These sites may be in response to a certain amount of sadness about the way Americans are positioned in the world. The cruelty we've been a part of," Wright says. "It's a backlash, I think. We need the balance. So these sites focus on our sense of humanity and compassion."
