SO, since I'm trying to break into astrology twitter (and I've had bourbon), let me tell you what I'm working on. I've been working on an app that will match people according to compatibility, astrological timing, "fate", and more. BUT, it's gotten especially interesting... ...because I've realized that timing is not just incredibly important for relationships--it's also much more codifiable than natal/synastry charts. Programmatically speaking, it's really easy to look at progressions/transits/solar arcs and extract the themes from a set of charts.
