Last week, the startup Xobni launched their public beta, so now everyone can get their hands on the Outlook plugin that turns your inbox into a social network. Xobni (that's "inbox" backwards!), taps into the hidden social network you spend time with every day: your inbox. The plugin runs in a sidebar where it analyzes and extracts info about you and your relationships.

During their private beta, they tweaked several things, fixed bugs, and even decided to streamline the plugin a bit by removing the "organize" tab, instead choosing to focus on their core product's offerings - super-fast search and relationship management. Using Xobni, you have access to features like threaded conversations, analytics, user profiles, a "related people" feature, shared attachments, and other automatically extracted info - like phone numbers for your contacts. To get in on the Xobni public beta, just visit the Xobni homepage and sign up.
