The biggest problem is the number of eyeballs. This site caters strictly to the card community, so only card collectors are looking at it. Kickstarter caters to most of humanity, or at least the Internet-connected portion of it. As a result, there's MANY more eyeballs looking at projects of all kinds.
The most successful crowdfunded decks didn't get that way because they sold only to collectors. They got that way because all kinds of people from all walks of life got to see their project and it sparked enough interest in enough people to make them want to invest.
Serendipity plays a HUGE factor in any KS project's success - strangers stumbling on your project, thinking it's cool and deciding they want in on it. Deckstarter and Cardlauncher both are missing that kind of serendipity. That, plus the fact that they've had a LOT of problems when they launched, is why Cardlauncher is struggling right now. They're also not bringing in the number of projects they want, I'm sure - they're running four projects right now that end within two weeks. When they're done, all at the same time, the slate is EMPTY unless something new comes along and soon. Of those four, the only one that's an unqualified success reached its goal only because the goal was so darn low, a mere thousand dollars. They'll get printed, but the card quality will likely leave much to be desired, while the other three haven't quite crossed the half-way mark financially but are more than two-thirds into the time limit.
