Diaspora, a social networking site that will be launching this fall, is trying to become a Facebook for people who like privacy:
Diaspora is a planned personal Web server that stores information to be shared with friends securely. Instead of centralized social media, such as Facebook, the server is meant to provide a more secure, decentralized network..."We believe that privacy and connectedness do not have to be mutually exclusive," says the team's page on Kickstarter, a site that offers projects for outside financing. "With Diaspora, we are reclaiming our data, securing our social connections, and making it easy to share on your own terms."
I don't think that privacy is necessarily a killer app these days, but maybe it should be. It's certainly becoming an issue for Facebook.
