I'm a great fan of the Impactstory service that makes it easy to aggregate all of your research output in one place, and then see how people are engaging with your research. I like it so much, that I signed up to be an Impactstory Advisor.
Today I'm giving a talk at UC Davis about Impactstory, and so that everyone can see why I like this service so much, I've made a video version of my presentation.
Visit the Impactstory website to find out more or follow them on twitter (@Impactstory). For an example of the types of things that Impactstory can track, have a look at my own Impactstory page (impactstory.org/KeithBradnam) .
