Social Geek is a chrome extension for referencing users /companies across multiple sites.
All you have to do is highlight the user/company on any webpage & click on Social Geek. As of now, you can reference in Github, LinkedIn, Stack Overflow, Meetup, Quora & Apache Jira.
Apache Jira will typically get you results only if they are contributors/committers to any of the open source Apache projects.
Had a chance to visit all the networking websites at a glance.
It is too good. Saves a lot of time especially with the look-up functionality.
