I can see a problem with this, when I open the link the URL remains the same (i.e. the "referrer" part is not updated). If I were to share it I'd just copy/paste the URL, in effect meaning that I won't appear as a "node" in the graph. I wonder if that's why the graph seems very "centralized" around a few points.
Unless it's because I refused to share my location. They should explain why they need it beforehand, I would never allow that by default (I only understood the point once I saw the map).
EDIT: Also, it will probably not take the retweets and similar into account, as the URL will remain the same. Overall it's an interesting concept but I doubt it'll provide any worthwhile data.
