I agree with this too. I think a more complex model of a horoscope is definitely what is needed to be accurate. This is has been often suggested to me that this site is too simplistic. However the drawback is that as you get finer and finer and more specific the numbers dwindle, and you loose the statistical power to get enough votes. In the beginning, we are forced to use the "newspaper" horoscope model, and many people that are in the know with astrology argue that such a model is too coarse at best. So as the site grows and gets more people voting, we will definitely expand to a more sophisticated model.
My hope until then is that when looking at the votes aggregated over many people of the same sun sign, the other variables will average out and there will still be a signal.
Thank you so much for joining! We have now been live for 1 month. I would say the publicity from this thread has been a huge boon for the site, so I greatly appreciate it.
