To help me figure out which features to use, I created a list of the top features and ordered them by importance. Then, I removed core features or the ones that every segment would expect a product like mine to have.

cperciva's achievements: interesting when you think about tarsnap's pricing model (picodollars etc)

as anchoring a month's service to the approximate cost of one missed appointment. This is something I come to again and again in copywriting and sales discussions, and it resolves pricing objections for almost everyone I've spoken to. The beautiful thing about that is that it resolves pricing objections at hair salons, who value appointments at $30 to $60, and at cleaning services, who value appointments around $80, and at repair services, which value appointments at around $200, and at health care providers, who value appointments at... oh goodness, you don't even want to know.

from "basic $9 / premium $19" to "freelancer $19 / studio $29 / agency $99"

cust. segmentation and research (phone calls to CEOs) to figure out what was important for each segment -- perceived value.
