Are they reading your fic?
Apparently!
But on the serious side, here's your actual problem:
Why is that a problem? Because people generally flock more towards stories by vets (people who have been around for a long while) than by newbies. Why? Several reasons. First, they have a better idea of what a vet writes like, so they have an implied guarantee concerning what to expect. Second, vets tend to participate more in a community, so people want to review the fics by the big-names of fandom. Third, it's a scratch-my-back-and-I'll-scratch-yours kind of deal. The more active the vet is in terms of reviewing, the more likely they'll get responses because, well, they're more likely to return the favor at some point. Fourth, if you're a newbie who never interacts with the community on an active level, that tends to imply that you really have no interest in sticking around for anyone else's story, so people are less likely to want to connect to you, as blunt as that sounds. You'd have to be particularly good to get readers if you make it clear you're just here to post your fic.
So newbies and non-active vets end up needing to work harder to connect with the general community in order to gain attention for their work. They need to participate in discussions, submit reviews, and cultivate a certain reputation. Of course, this doesn't always net you a following. Still, it's a good way to make friends on a writing community, and friends = reviews. (Note that the most popular fics in the forum are also the ones written by people who have plenty of active friends.) That and if you slap a link or banner to your fic in your sig, you net readers
that way via advertising every time you post.
Of course, in the meantime, if you're
really that worried about reviews, be more active in
getting them. Go ask reviewers to look at your stuff. Participate in the
Review Game. Sign up for the
Review Exchange. The last thing you want to do is complain that no one's reading your fic because, honestly, that tends to reflect badly on you as a writer (i.e., you end up sounding like you're demanding people to read), especially if you haven't really posted that much in the community. Not to put it too meanly or anything, but yeah, it's harder to get people to take you seriously if you do that.
Whatever you do, good luck, and hang in there!
