Design Where You Post
Artists are often told to keep their audience in mind when they create. Seldom, though, does anyone go into any practical ways of doing that.
In Walter Murch's excellent book on the topic of editing film, In the Blink of an Eye, he mentions how sometimes he will tape a cut-out silhouette of an audience to the bottom of his window to remind himself how his work will eventually be experienced.
Consider how this can be extrapolated to your own work. What subtle way can you remind yourself of the people you're making the experience for?
One idea would be to write or draw directly on a screenshot of where you plan to publish your work. In addition to keeping your audience in mind, you can see how the site's color scheme affects the mood of what you're making. Use a tool like the Chrome extension Fireshot to take a full length capture of a site.
You can make your storyboards on a screenshot of YouTube, doodle directly on deviantART, or write your story on the fiction site you plan to post to.
If you're writing traditional printed media, this happens to be one of the benefits of using a typewriter. When you read your work back, you'll always be about as close as you can be to how you're readers will experience your work.
There are a lot of things you can try, now that you get the basic idea. Play around and see what works for you. Good luck, and keep exploring.
