That's part of the 'Robin_Message's points here on this thread and it is a valid concern. We want to focus on small circles inside employment network, where your Director and you end up being there independently. Yes, the chances appear to be low, but we don't have a time limit.

Just think you are running a Scala or Ruby development team, and regularly meet a lot of developers in conferences. You are a small group, and you are connected to each other. However you don't want to offer jobs explicitly. In such cases Jobrupt may help. It's our hope, and it is still an experiment.
