What I get from the article is that this guys had an idea and 24 hours later they created the Kickstarter. This is partly wrong, what is totally wrong is people supporting them(please note this is just my opinion) because you can find everywhere cheap shirts, even good ones. There a huge market about it what would make you think that some random guy can do better? Just because they say so? If this would make any money companies would have already adopted this.
When approaching Kickstarter I think one(with an idea or a prototype) should make it clear what he wants to achieve without the "I will make the best at the lowest price" attitude. Remember the users that backing the project it's a donation with a possible gift and not a preorder. Also you should have thought about it more than 1 day. The day you realize that you can't maintain your promises your reputation might end up destroyed.
I think that it's important that we use Kickstarter the correct way because we risk ruining it, when too many people will realize that they will not get what they paid for people will not use it any more, resulting a bad reputation for kickstarter and therefore other projects that might be worth checking.
