Workshop interfaces typically greet users with a blank canvas, requiring them to envision their results in advance. However, as Jakob Nielsen argues, not everyone is a Michelangelo who might readily see a statue hidden in an uncarved marble block. Professional looking templates can help users by providing them with guidance and inspiration.
The problem with these templates, however, is that they are unlikely to provide genuine creative inspiration. As they come bundled with a million copies, by necessity they have to be in line with very common, widely accepted ideas. Although technically well crafted, they are not genuinely creative.
Inspiration, as important as it is, does not have to come from templates anyway. It can come from a good book or a walk in the park. Getting inspiration is a very personal experience and while it is always good if an application can do more, it does not need to give inspiration as well. However, it should certainly allow users to get an idea onto the canvas.
