Meh. I don't agree with astrology either, but I think it's fun, and I know quite a bit.
Here's an easy way to figure out compatibility without getting too technical: there's 12 signs. They are divided into four elements, water, fire, earth, and air. Typically, the signs within the same element get along the best (although with some signs, that is not the case), and the signs with a compatible element get along pretty good.
In the water group you have: pisces, scorpio, and cancer.
Earth: taurus, virgo, and capricorn.
Fire: aries, leo, and sagittarius.
Air: gemini, libra, and aquarius.
Water and earth are compatible with each other, and fire and air are compatible with each other.
Water and air are probably the least incompatible with each other, as well as fire and earth. Water and fire are okay, and earth and air are iffy. (I'm a water sign, a scorpio...hehe...)
Therefore, since you're an air sign, you get along well with fire signs. Aquarians would like Aries, not just because they are compatible elements, but because they both have a light hearted approach to things; both are very communicative and social. Then again, Aquarians tend to get along with most signs.
Supposedly, my so called worst matches are Libras, but I have a ton of Libran friends that I get along with...so, to me, astrology doesn't have much credibility in my life. But it's still fun.
