Thanks for the interest Karl. I am sorry, but it doesn't yet support google+ profiles. Also, you should probably link to: https://plus.google.com/u/0/101556315529391051445 , as your original link[1] gives me a blank page.
Edit: In the mean time, I'll probably add support for the entire leaderboard, focusing only the standard HN profile. No photos though...
It is updated automatically with time, so people don't need to worry about particular requests.
