That way people could add their ideas without being fishboned. Let's think of a few examples of the quality of ideas which would have people clutching their sides with the hilarity ..: 'A scuba diving suit that can fly' 'shoes which double up as spare tires' 'A restaurant which turns upside down now and again .. hohoho' 'A man that follows you around and does your swearing for you, so you don't have to' 'instead of walking, everyone could hover everywhere'

You get the idea!

Or alternatively just a tickbox author-selectable against each idea .. which is checked if the idea is 'just something really stupid that has no chance of ever working - but I can't think of anything at the moment, and I just want to 'add' '. That way no-one has to bother reading it.
