It has helped us to find new partners quickly, as well it's an easy way to track them once they are onboarded into our program - so we can see their performance over time! I would like more flexibility with what is available through this tool (like being able to create custom dashboards).
We have been using PDS since its launch by Pubcon last year; there was nothing else out at that point from all publishers who were looking/planning ahead about how best to get started monetizing social media sites effectively via affiliates or other revenue streams.
