I believe you used to be able to click on the "forks" and "watchers" button to see who is forked or watching. Now the button defaults to "unwatch" when looking at the project page.

I find these new icons confusing as well. It took me a long time to figure out the one icon was an eye with a "X" on it for "unwatch". Not sure why the branches in "your fork" travel upwards as well, as I've never seen a source control diagram do that.

And my default user/organization/project icon is no longer an octocat but a book with a fork on it. I miss the octocat.

I think this is a classic problem when a graphic designer doesn't have enough meaningful real work to do :)
