Sure. You are on.

It is updated automatically with time, so people don't need to worry about particular requests.

I've just updated my HN profile with a Google+ profile link at the VERY end of the profile.

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...

How often updated?

About once every hour.

Thanks! Awesome job.
