Or else, it isn't implemented. If it isn't, it'd be a nice feature to have.
I see the same behavior as at the RhodeCode demo site. Go here:
and click on either the followers or forks button; there's an anchor, but the URL is just a #, so the button doesn't do anything. It'd be nice if it showed the list of followers, or the list of forks.
I tried this in Safari, Chrome, and Firefox.
Outstanding bit of code, by the way. Very well done.
