The notion that venture capitalists are somehow "in the way" here is highly specious.
The simple fact is that no one on Kickstarter is there for any reason other than "we want your money because no one else would give us any."
This can be new start-ups with more dreams than schemes, venture capital won't touch them because they have zero experience in doing what they are doing. The idea that "I've never done it, but how hard could it be?" should -and does- raise alarm bells among the sensible.
The second group of Kickstarter money seekers can be classified as the "glorified pre-order" group. These are the established companies that use Kickstarter to fund their normal course of business. The return on investment is too low to justify VC funds, so companies come to crowdfunding as a way of avoiding negotiations with their bank, that is all.
Somewhere in Kickstarter are some interesting little projects (usually local arts projects) that genuinely benefit from this model.
Any VC who would put his clients' money into some of the high risk, high profile Kickstarter projects (I'm looking at you, Ouya) deserves to be fired - which is why they don't. There are no projects on Kickstarter that operate in the VC sphere. None.
