My dh is way into pirate, jessica, and donald pins. DD is pirates and tink, some things with Japanese lettering on them, DS floats around with Buzz, pirates, stitch, peter pan. I'm into tink with attitide, parks I've been to, rides I like and a few others that strike my fancy - I just paid way too much for a pin on ebay b/c it had chili peppers on it and I collect those too.
I have some older winnie the pooh I picked up when DD was little b/c she liked pooh, but has no interest now, so most are on my trades page.
