My suggestions to increase readership:
1) Update frequently. It took me a while to build up a core of readers.
2) Read other story hours and post there. Most SH authors are readers as well, and if you read their work, they may give yours a look. Note this is not quid pro quo, and it's rude to expect this reciprocity as such.
3) Post actively all over ENWorld and have a catchy link to your SH in your sig (note: I'm not advocating spam, have something good to say, in other words, be active in the community).
4) Write for yourself, and not for your "audience". If you write solely for accolades and not for your own personal fulfillment you'll only find disappointment. Try and write something each and every day, even if it's just a "junk" paragraph. Often when I don't feel at all like writing and force myself my best stuff ends up coming out (even when it needs lots of editing later).
5) Remember that far more people read these things than post comments.
6) Practice, and both read a lot and write a lot. Consider this a long-term project to improve your writing skills. For me, when I started writing I had the most difficulty with dialogue, and tried to work on this particular area. Developing a good style that draws the reader into the story takes a long time. Read those popular stories noted by Enkhidu, and lots of other fiction. Try to find your own voice.
Don't get discouraged. I've collected over 80 rejections from agents and publishers for my novels, but I still love to write, and it's a great skill and hobby to develop. Plus it helps in "real life" as well...
