In this short talk I cover some research highlights from the 4 Pi Sky project, including recent successes in fast radio follow-up and exploratory work on the potential of radio observations for transient classification. Finally I introduce our work on making the VOEvent standard more accessible to the astronomical community, with the long-term goal of enabling more optimal automated follow-up strategies.
