My research aims to understand how people use different social media and online services and how this is reflected in the spatial footprints of users. To get to this point, I need data, reliable data... and lots of it. This is how you can help! I'd like to ask you to share your online profiles with me so I could conduct my research on a large database that allows to come up with meaningful conclusions. On this website, you can authenticate with different social media providers and authorize my research tools to collect some information. I am interested in looking at how different online activities are across services, so the more of your profiles you share, the further my research goes.
