Ask HN: Strategy for distributing promotion codes
A valid promotion code will remove any restrictions for a user, the same as paying for an account upgrade would do. My plan is to create promotion codes tailored to specific bloggers and email them with a short pitch and the promotion code, which they can distribute to their audience if they choose write about it. I'm not sure how many free account upgrades I should specify per promotion though. Too few, and I worry it'll be ineffective; too many, and I fear that no one will need to pay to upgrade, which is the ultimate goal.
Any suggestions?
PS. To show my thanks to HackerNews for its guidance, and to celebrate the introduction of promotion codes, I invite you to sign up for my web app, Preceden, a tool for making timelines, at http://www.preceden.com and upgrade for free with a promotion code of THANKSHN, which will let 5 people upgrade for free (maybe I should have made it 10...)
