Yikes, on the one hand this sounds like a very useful search tool for technical recruiting. On the other, it sounds like its usefulness depends on how many members of your team you sign up for it...and once someone is signed up they scrape all their data and add it to their "database".
Although the social connections feature is really helpful, there are lots of other ways you can use Sourcing.io to search for engineers. There a lots of other ways to filter the data: location, project contributions, language experience, current employer, et al. For example, to find people who might be a fit for your DevOps role at Perfect Audience, you might want to see all the engineers that had contributed to Graphite's web app (https://github.com/graphite-project/graphite-web) or have lots great DevOps people following them on Twitter--we try make these kinds of searches really easy to do.
