Chime.in, which makes its public debut Tuesday, shares some similarities to Twitter’s interface, but UberMedia CEO Bill Gross argues that his social network tackles completely different problems than Twitter or Facebook. Unlike Twitter, which describes itself as an “information network,” Gross describes Chime.in as an “interest network.”
Like other social networks, Chime.in lets users share content with others. It has a newsfeed, profile pages and a system for following other users. The social network doesn’t have status updates, though. Instead it has “chimes,” which are a cross between a Facebook status update and a blog post."
