Beyond citations: The impact of your research measured by "ImpactStory"

Following a recent discussion with a Rhodes academic on the impact of his blog posts I decided to investigate this recently-developed (2011) tool which goes beyond traditional publication citation counts. After a simple registration process researchers may seamlessly import up to 1000 publications/data sets, etc.  What metrics are measured? (Mendeley, Cite-u-Like, PLoS and many more). 

ImpactStory is an open-source, web-based service that is designed to make it quick and easy to uncover the impact of research output. Being philanthropically-funded and not-for-profit, this project builds on the belief that open altmetrics are key for building the coming era of Web-native science. (FAQs)
