After much debate on the Venus ruler question, she finally did a test for it. I'll be updating this post too.
I tend to think this is a pretty rididculous argument though. Earth is a NEUTRAL PARTY in this thing. We're talking about how the planets go around Earth because we are on it. It should NOT be thrown in as something else to analyze. Ergo, I think Earth shouldn't rule anybody's one sign, thanks. (Speaketh the Taurus who finds this impractical, and I don't think Taurus and Libra are utterly unalike and unable to relate to each other either. If you're gonna go there, why don't you pick on Gemini and Virgo? And even there that isn't utterly out of the question.)
