I'm an avid reader but unfortunately not such a good writer. My thoughts are too chunky (ergh, not smooth like) to put in paper well.
For a long time, I have been reading Harry Potter and Wheel of Times fanfics. In fact, I started reading fanfiction through HP. Then, I got caught into Gargoyles, X-men, Kim Possible, Buffy the Vampire Slayer, Fullmetal Alchemist, CSI: Las Vegas, Law and Order, Star Trek Voyager (to let my inner geekness fly, lol), Stargate and Sailor Moon. Oh gosh, I don't know how I find the time to read around all these fandoms. Granted, more and more times, I've been reading updated fics that I've been alerted to by email. In 2009, I caught myself reading Avatar fics with Azula or Ty Lee in them as main characters. Recently (2012), it's been all about Devil Wears Prada and Once Upon a Time.
"Fallen" by ConfusedKnight is the only fanfic that I've read that is in Tamora Pierce's world/fandom.
Favorite Characters (therefore I mainly read stories where these characters are the main ones, with some exceptions)
Gargoyles: Demona (Love Kudara's fics)
X-men: Storm, Jean Grey, Emma Frost (got converted by Princess Alexandria), Wolverine (if done well).
BtVS: Faith and Willow
Sailor Moon: Rei
Avatar: Azula, Ty Lee, maybe Toph
DWP: Miranda Priestly
Once Upon a Time: Regina/Evil Queen
