I'd like to reach people organically, and it means something more when you get to talk to the people who are using it. I'm not looking for downloads or upvotes.
Posting on HN and offering money isn't exactly the definition of organic traffic though. That said, good luck to you, I hope you find people who try it!
You have me there!
It's hard to get volunteers, so I hope $15 incentivizes them. Thank you for your support!!
