Let's talk after you start paying. I'd love to hear how you're using it and how it's providing value for you—and even get a testimonial for the frontpage! :)
FWIW there are multiple tiers: $8/mo, $35/mo, $85/mo, $275/mo and I have one custom-priced "enterprise" client.
That's another lesson I learned: The kinds of feedback I get from paying customers vs drive-by trials is completely different and often opposite.
