IMO, Astrology is pseudo-science and not reliable. Same with Tarot and other practices. Yes, I read Tarot -- I've never said it is a science, infallible or reliable. Yes, I've has my chart done by someone I respect in other arenas, but I maintain that in my experience, astrology, tarot, the runes, pendulums, et cetera ad infinitum are ways to get you to pay attention to your subconscious -- the part of your brain that processes things while you're not paying attention.
To those of you who are flailing wildly at the idea that you now have to readjust your personalities and daily lives to reflect your new signs: I really hope you're being facetious.
