Honestly not sure. I've never had a post rise this quickly, though it's definitely fun to watch! Here's a screenshot of where people are visiting from: https://i.imgur.com/Of5xKOk.png

What did you use to generate this?

We're using piwik(https://piwik.org) for analytics, which has a nice map view.

I'm really surprised how few visitors were from the bay area, is that normal? Does anyone know the location breakdown of hacker news visitors?

Edit: oh that was at 6am PT

Perhaps it's just that great an idea :) Quick, grow and monetize it!

Take a percentage cut of the stickers (or postage cost)

Weeeeelll...if postage is 49 cents and people mail in 50 cents, that's your immense profit opportunity right there ;)

Indeed, and they don't have to tell anyone what the postage actually costs :)

I agree, especially with the tremendous amount of votes... Usually for the first 30 minutes or so you'll be lucky to get a handful of votes, which rapidly accelerates your post.
