That's pretty freaking cool! I'm really impressed by this. I will say that even in Chrome, things are a little too close to be understandable, and it might be better not to show EVERY connection- just the stronger ones. Still, this is very impressive! (As I said before!) It would be awesome to be able to search users! In fact, I don't know how mk feels about this, but this would be a really useful page for the site to have under "community"! It gives way more information about who's popular, and with a bit of tweaking could quickly show off the different communities we have. I am wondering why there are a lot of smaller users who are only following the heavies, but I imagine that's because you're crawling the site by going through the Followers of the followers of the followers of one of the popular users.
Thanks for the kind words. Looks like it just completed a batch, so the state it's at now is with most everyone on the site. I just changed it so when you mouse over a node, it will hide all nodes that aren't directly connected to it. It makes things a little less busy. So if I want to see a group of the circlejerkers, that mostly revolve around ytknows, I can mouse over his name, and it's pretty clear to see that it's a well defined community that doesn't really include other big names from around the site.
I could definitely add a search feature. Or, could begin classifying the graph into clusters based on a number of different factors. Previously I did one for reddit subreddits, based on betweenness centrality. Either would make it more understandable, it's definitely a bit overwhelming at the moment.
Might be better to do that when you click on someone? Ideally when you left click on someone. It got a lot harder to surf around the map now, and it's way laggier. Apparently, I'm never satisfied. But I swear I think that this is cool!
