Well, it's really easy to handle this kind of issue. That its not really a problem. One advice I got from a mentor is that we sometimes instinctively know something, and act on it, but rarely arrive at a proper judgment on those "psionic emanations from the khala." 
 
What's required is to be able to pick up the good pieces you like best, the ability to scrap, throw away something, even if you'd invested emotion and energy into it. The idea is that every undertaking brings growth in the person, it's the will to use and dig into that "seed" that makes the difference.
Writing scripts and developing stories is a long process. Sure, we can just throw away anything at our fans, but the idea that you want the best for them makes a whole world of difference. And besides, most of your fans would want it now, but then critic harshly later. (or, maybe not)
Anyway, the tldr is this: (and I hope to help)
1. If you really want what you're doing, and enjoy it, do it for your sake. Others can join in on the fun later.
2. It's not bad or wrong to scap an idea or work you don't like.
3. Learning comes in both success and failures.
4. Expect less from your audience's input, as they are the audience.
5. "Destiny is the shelter of the weak; Fate is dictated by those who have power" -- Vicar Setharun, of the Dae'Uhl Tribunal. 
 
  
Anyway, as for dealing with lack of community action, I've come to a sort of justification that most SC fans right now are really in a great deal of stress waiting for SC2. Thus, it might be natural that their desire is quite fixated on SC2. As consequence, you might notice some bumps. They're still so into SC2 and that having no real satisfaction from both story and gameplay, it is natural that things are quiet on our end.
Anyway, I'm sure Omega's a tank, and man, I'd feel sorry to lose one more Campaign Maker.
Sorry for the longest post, guys. Maybe, just maybe, someone could get some additional pylons from reading the above.
