Really cool. How do you pull the information? I feel like this is well known given some of the stats that have been done on hubski recently. Not to put more work on your plate, but what would be more interesting than a directed graph would be weighted graph based on interactions. So every time I replied to your comment, shared your post, or tagged you etc it would add to the weight. And here is me: Looks like @newgreen@, mk, and insomniasexx hold me in suspension in the middle.
I pulled the information by just going from user to user. So it starts at a user, then enqueues all the followers and followees while adding an edge for each one. Then it pops the next user off the queue and repeats. The script wasn't more than 50 lines of (python) code. A weighted graph would be cool. It would be a little more involved, and it would need to examine much more information. Also, I'm not sure what the options for visualizing a weighted graph are... But, yes, a directed, weighted graph would be more telling, no doubt.
I will always hold you, my sweet hubski lovers.
