Macro, Nature/Wild life and Landscape. in that order. Those are the one I enjoy most, for some reason I dont like portraits of people but thats just me.
so i have gotten/still getting into....events, portraiture and pet photography. would like to do models as well, but later this year as it warms up outside and less attire becomes all the more prevalent. 
I'd have to say journalism in general, although I really like senior portraiture a lot too. I shoot a LOT of sports and I really love it. I thrive under the pressure of weddings. Too bad my body doesn't! It'd pretty brutal on your feet, legs, hips, arms, shoulders... everything! Might help if I lost 30 lbs.
