Hachi is a bootstrapped startup that’s looking to aggregate users social connections across LinkedIn and Facebook, with Twitter, Google contacts, and Outlook address book integration said to be coming soon. Unlike LinkedIn, there’s no limit to contacting those three degrees of separation or closer. Also, the service allows cross-network connections when looking to meet new people. Hachi gives each path toward contacting a given individual a “Path Score” on the basis of the strength of connection between each person in the path. [Source Techcrunch]
