That's really interesting information
I've been thinking about the mission of this site. When Orrery becomes more polished and detailed, perhaps move its link to a more prominent and visible position in the site (top of page, maybe center of the banner?) so it is easy to find and one of the first things people see when visiting.
Another idea, along the lines of the Library idea Pebble had, would be to make the site a continuously updated resource for cutting edge information on exoplanets, or perhaps more specifically exoplanets in their stars habitable zones. An online Exoplanet Library with links to published articles and deep dive information about various exoplanets.
Just speculating on ideas to attract potential high quality membership.
