When you build a product, a lot of factors can lead to its success. One of the hardest to quantify is "Fun". Is your product actually enjoyable to use? Will people talk about it because it's simply awesome? Having worked in games for years, I've been able to take the lessons of adding Fun to a video game across organizational boundaries. This is an incredibly difficult ingredient to measure and add to your product, whether it's an app or a piece of IT infrastructure. This is not a usability discussion, or a talk on metrics. Its about using a large toolbox of concepts and ideas to add the ephemeral quality of Fun to whatever it is you are building. If you're making a product that needs to compete for attention, consider adding fun. It is not the easiest element to find and inject, but it can be one of the most powerful in determining your product's success.

Entrepreneurs chase after this a lot, and it's incredibly difficult to find. One does not simply "Add fun". If your product is clean, engaging, and usable, it can still fall on it's face in the market. People who are starting new companies need every advantage they can get, and having an product or app that is more fun than your competitors can make all the difference.
