I agree with what everyone else said. Tapas doesn't have a large community for stories right now, so it will take time to get a following here. Also, it's a lot work to get noticed. You need to balance writing, reading other people's work, being active on the threads, and responding to your readers.
However, anything worth having you need to work for. Like other person said, if your work is good, you'll New & Noteworthy or the Daily Snack. I've noticed that with most writing websites, getting featured is your ticket, so post your work and keep improving your craft. Eventually, you'll get a following.
My readership is small, but they show my stories a lot of love =)
