For the past year, I've been building a simulator for personal finance called ProjectionLab (projectionlab.com)
It goes pretty far beyond the standard retirement calculators, and is finally at the point where I'm seeing better than minimum wage on all the time I've invested on nights/weekends.
Perhaps this doesn't quite fit with the "not talk about them" part of your question though. Past feedback from the HN community has been a huge part of shaping the development roadmap and keeping me energized about the project.
