A bitter taste in the mouth

Kickstarter has proven a very valuable means for many creative types to realise their visions, but the backers of some projects seem to forget the element of risk and the fact that there's no guarantee of a return on investment - as illustrated by the tale of ZPM Espresso. So if you're ever tempted into parting with cash, it's best to go into it with your eyes open and your expectations in check.
