Actually, @andrew0, astrology holds a lot of weight when studied properly. The form that it is in as it is presented to the masses is a massive distraction. Firstly, the use of tropical astrology basis its planet's positioning where the planets were 2000 years ago when Vedic astrology began. This does not take into account procession of the solar system through the galaxy, changing our north oriented star over time. Sidereal astrology however allows for the positioning of where the planets are now.
Here's a neat experiment that was conducted to show that the planets' positions do cause an effect on objects here on our planet: http://www.sciencegroup.org.uk/capdyn.htm
Thanks for your feedback, I will check the link and let you know :)
