LiveJournal: You Are Here. This is where I post my blogs.
Facebook: Most of my Facebook is public, but if you're just looking to follow my writing, check my author page instead.
Twitter: I sometimes talk about writing updates and little bits of life that aren't big enough for a journal entry here.
Instagram: This is where I'm most active these days. I post nature photos, hauls, what I'm reading/watching/playing pics, and my wonderful guinea pigs!
Tumblr: I reblog content from my numerous fandom interests here.
Published Works List: If you're interested in checking out one of my books, this is the place to look.
My Online Writing List: This is probably the easiest way to find my all of my writing that is currently hosted online. Fanfiction and short original works are linked here.
Facebook Author Page: I update readers on my writing here, but I mainly save this page for bigger announcements not frequent updates.
Amazon Author Page: The easy way to find my books for Kindle.
Smashwords Author Page: You can find my books in many formats here, but you'll have to get them onto your device manually.
Wattpad: I posted a short serial called Doubts here.
Fiction Press: The place where I wrote my first short novel. It's not up anymore, but there are still lots of songs and short stories.
Fanfiction.net: Where I first started writing. *Sighs* Memories. You can find my fanfiction here, though the very old stories have been removed. (Too many Magic Inc. spoilers!)
AO3: This is the new place to be for fanfiction, so I moved all my fanfics over here as well.
Writing.com: I have a few original pieces hosted here.
Giant Bomb: The best site about video games. Okay, it is a small team, but they are awesome. They make lots of funny and informative videos, but watch out for a lot of cursing.
Goodreads: A place to keep track of books. I keep it very up-to-date, so you can always find out what I'm currently reading there. I also occasionally write reviews.
LibraryThing: I don't keep this site as updated as my Goodreads, but I do check in here and there.
Last.fm: I keep track of my music listening here. I kind of like charts and graphs when I'm not the one making them.
Trakt.tv: Want to know what movies and TV shows I've watched? This is a great place to do that.
Grouvee: This site uses info from Giant Bomb to allow you to make even better video game collection lists.
PSNProfiles: I love trophies, don't you? PlayStation trophies, anyhow.
Fragrantica: A site to keep track of perfume. This site turned me into a perfume addict. Seriously.
Pinterest: I pop in occasionally to save some pretty pictures and recipes I'll probably never attempt.
Spotify: I listen to a lot of music. Here you can find my playlists, including my story soundtracks!
YouTube: I almost never post any videos. I just watch a lot of them.
DeviantArt: Much like YouTube, I use DA more to keep track of things that other people make.
Online Game sites:
Neopets (sign up here): I've been on Neopets almost as long as I've had access to a home computer.
Gaia Online: I go through stages of loving Gaia and basically forgetting it exists.
