Hi. I'm on Wattpad and I've just added you. I find on there it's difficult to get reads, but I don't let it put me off. As for on here, you can post your fanfiction and sometimes you'll get feedback. It can be a little frustrating when you think no one's reading, but I suggest post in as many places as you can, and don't get discouraged! I post here, Wattpad, Serebii's forums and FFnet. I find FFnet is the best place since people can leave quick reviews and you know if someone is reading and enjoying when they add or fave your story. Whereas in forums you only have the 'views' to go off and you can't be sure those readers are sticking around for the whole thing.
The tips I can give you is to read and review other's work, advertise in your signature, gain more visibility. I tend to lurk, but I have met some cool people in writing forums, FFnet and Wattpad. Add a writing buddy. I'm happy to chat writing with you and give advise any time! I tend to check the forums daily just in case I have a PM.
Again, don't get discouraged. Write for the sheer enjoyment of writing. I love writing and I love writing for others and it's reads, faves and reviews that keep me going. But if I didn't enjoy the story I was writing then I wouldn't feel like writing it at all. If you enjoy it, keep going. If you're enjoying it, then your readers may also be enjoying it. Also remember there are silent readers. Not everyone has something to say. Maybe they're shy and don't know what to say! Above all, the more you write - and read (we all learn from somewhere) - the more you'll improve =D
