I voted family / kids / newborns because I mostly want to take pictures of my daughters and family.
However, I enjoy taking all other types of pictures listed. I would add sports / action to the list. Probably, a majority of my photos are either landscapes or sports, because I'll tend to take a lot of photos when those are the subjects. But my main GOAL is to get good shots of my family. And of course, the categories overlap I'll take portraits of my family, sports shots of my family, even macro photos of my family (eyeballs are fascinating!). Who knows, maybe in the future I'll take some Astro shots of a member of my family in orbit.
