"Shouldn't we be glad to have Venture Capitalists cut out of the loop so that companies actually listen to us?"
I like the concept of Kickstarter, and have donated to one of the projects over there myself, but nobody should go into it thinking it makes them anything more than what they already were to the company: a customer with a potentially open wallet. One could argue that you don't even have influence on the company, because they've already decided what they're going to try to bring to market; your only role is in deciding whether it's something you want.
In a word, I would argue no. Primarily because you are a customer with Kickstarter, but you are an investor with venture capitalism. In a way, "investors" in Kickstarter projects are getting a raw deal, because they receive only the product (which you could buy eventually anyway, if it does come to market), but with venture capitalism you receive an ongoing share of the profits of the company in exchange for the risk of giving them money. The scale of the investing is also a key point in this.
I can see how Kickstarter is motivating the comparisons, because there hasn't really been anything exactly like it before, but the two roles are not the same.
