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.
