1. Yes, we are honoring that! It's a reward for being an early adopter and it's important to keep the community "starter culture" intact as we move to a paid membership model.
2. We don't want you to have to trust us. That information will be transparent. Check out our current writers leaderboard [1] as a prototype of how that will look. Minutes reading to completion is our basis for payments to writers so you can imagine a pie chart on your account page that shows who your $5 went to for that month in addition to a community-wide distribution that would look similar to the current leaderboards.
As you can imagine there will be cases where we can't get in touch with writers or they're not interested or something like that. We'll probably have to have some sort of time-out period where the uncollected funds might be reallocated to writers who have verified with us or something of that sort. The important thing is that we're committed to making these rules and decisions transparent.
