There does seem to be a difference though.
Some of the earliest kickstarters I kicked into fell into two buckets.
1) Something like "We want to make a second season of our video series, please kick in, we've got rewards at various tiers." This is great...I'm not really buying anything because the reward values are less than what I am paying. Also, they were generally making followup work or were established people starting a new project...so you knew what was coming.
2) Some craftsman wants to make something cool, but maybe he needs certain parts or materials which have a large order minimum. So he does a kickstarter. If at least 150 people want to buy one, he meets the minimums and starts working. If not, everybody gets their money back (like any unsuccessful kickstarter funding).
I know there is a place for the more ambitious projects. But they tend to get much further away from #2. They are no longer a leatherworker who needs a bulk discount on brass hardware to be profitable or a board game creator who has already completed their game but can't find a printer that is going to do less than 500 printings for a reasonable price. Instead they are people who maybe have a working prototype for some complicated electronic device, but they don't have a finalized design, and they definitely don't have working software to control it...they hope to pay for that with the kickstarter funds (I bought something like this...it eventually got delivered and the physical product is high quality, but the software was borderline unusable so I eventually gave up).
At that point you are asking for venture capital from strangers who have been promised an actual product--you are doing preorders without an obligation to deliver. Make your product sound really cool but set your funding goal low enough, and plenty of people will sign up.
