Don't listen to these anons, they're retarded and jaded by Homestuck's failures. Hiatuses are a fact of life that every writer must deal with at some point or another. Even South Park, which has a ridiculous turn around time, takes one or two breaks in a single season, and of course takes off a few more months for the writers to cool down and work on shit.
If you're going to make hiatuses in your work, do it, but make sure that your actual update schedule is consistent. If you must stop working on your comic for an extended period (say a year), bring your story up to an appropriate point first, and just understand that by doing this you're basically killing your fanbase off slowly. >>88652617
Make something good first. Homestuck (and really most things that get big) works because it has a distinct premise that captivates and inspires audiences, and a cast of good (not necessarily likable) characters, and the people will come.
The truth is that the internet is shit for criticism. On Reddit and Tumblr, faggots just follow the circlejerk for internet points and reblogs, so their opinion is basically worthless, and on 4chan contrarianism is the only way to get (you)s reliably, so our opinion is basically worthless.
Make something good, then worry about fitting into some arbitrary niche. If it doesn't catch on, keep making good things, and sooner or later one of those good things is going to get you noticed.
