I posted a video about Harry Potter shipping about a week ago and a blog post about Hunger Games shipping four days ago.
When it comes to Twilight, I only have one really strong shipping preference: Leah and Embry. (Yeah, random couple. I know.) Still, I'm way more likely to read fanfiction where one or both of them is with someone else than I am couples in other other fandoms. I'm not really sure how I started shipping Leah and Embry. I used to ship Jacob and Leah, and I think I found a Leah and Embry fanfiction that was written by an author would also written a Jacob and Leah fanfic. I'm not entirely sure why, but I really liked them together. They've also become my two favorite characters.
Other than that I really only ship canon characters, and I'm using the word ship losely there. I don't really seek out fanfiction about that many couples. Most of the fanfiction I read has one, some, or all of the members of Jacob's pack as the main character(s). Other than Leah/Embry, I'd probably just consider myself a big fan of Jacob/Nessie and Quil/Claire. I like Jared/Kim, Paul/Rachel, Sam/Emily, and Alice/Jasper as well, but I really only read fanfiction about them if I happen to stumble upon it. I am reading a pretty awesome Paul/Rachel fanfic at the moment.
If you're a Twilight fan, what are your favorite couples?
