We're excited to announce that Sean Gillies, author of Shapely and collaborator on the GeoJSON specification, is joining MapBox! Sean is going to bring his algorithmic wisdom to all parts of the MapBox stack, and help build our next-generation open source tools.
We've long been fans and users of his projects - we use Shapely for basic analysis tasks, and GeoJSON is a pivotal standard that makes our markers API possible. It's going to be an awesome future combining Sean's analytical background with MapBox scale.
