Dropping a comment here because of all the down votes. I agree with them. I come to HN for interesting and thought provoking articles, or for interesting news. Pen-and-paper mining is awesome and is totally in the spirit of HN, but single word jokes about "organic" and "fair trade" Bitcoins are clever, but HN is just the wrong place for that. I'd much rather read comments about attempts of other types of cryptography on paper, or perhaps some history about paper based crypto, or anything that adds factual or newsworthy value to the article. Jokes are neiter factual or newsworthy, and I feel are out of place here on HN.

Thanks for understanding.
