How to get "fans" for my writing?

[halley]

I'm fifteen years old and really ever since I was in fourth grade, I've known that I want to be a successful writer. I wrote short little stories then and read them to all my friends, and now that I'm older, I post a lot of my writings online. I write fanfiction because it's a huge base of people with a mutual passion for something (either the real series or the spin offs of them), and I've been getting a lot of response on my latest stories.

I feel like I'm slowly starting to get somewhere with it. I've had a few people in school come and tell me that they love it, and I reached one hundred reviews by about chapter three or four. But now that I feel like I'm starting to get somewhere with my writing, I feel like I need to get "fans" who support my work. I don't want to come off as arrogent by making a facebook page for myself - I have a twitter and tumblr, though.

It's not just fanfiction that I write for. I write for myself, and a lot of those end up on my blog. I also post stories on Figment. Most of my things are long works, though I do have quite a lot of poetry and short stories as well. (:

Does anyone have any suggestions for building a stronger fanbase for my writing? Thank you so much!
