This week I read a post of Joel Spolsky, the CEO of Stack Overflow. This post talks about the term “simplicity” when we refer it to a software product. There have been an old ‘80/20’ rule meaning that 80% of the people use 20% of the features. So, you convince yourself that you only need to implement 20% of the features, and you can still sell 80% as many copies. Unfortunately, it’s never the same 20%. Everybody uses a different set of features. In a period in the past, dozens of companies tried to release ‘lite’ word processors that only implement 20% of the features. Most of the time, they gave their program to a journalist to review, and the journalist reviewed it by writing their review using the new word processor, and then the journalist tried to find the ‘word count’ feature which they needed because most journalists have precise word count requirements, and it was not there, because nobody in the target 80% would use this feature. The journalist ended up writing a story that attempted to claim simultaneously that lite programs were good, bloat was bad, and he could not use this program because it would not count his words.

Making simple with 20% feature products is an excellent bootstrapping strategy because you can create them with limited resources and build an audience. So, you sell “simple” as a wonderful thing and coincidentally, it’s the only thing you have the resources to produce. Bootstrapping strategy has advantages in certain situations, however, it would not be good for long term strategy because there’s very few obstacles to prevent the next two-person startup from cloning your simple app, and because eventually you can’t fight human nature of wanting the features.

Success is a result of a combination of things: building an audience, evangelism, clean and spare design, emotional appeal, aesthetics, fast response time, direct and instant user feedback, program models which correspond to the user model resulting in high usability, and putting the user in control. All of these features share a common character of having benefits that customers like and pay for, but none of them can really be described as “simplicity.” With many years of experience running his own software company, Joe Spolsky saw that nothing he have ever done at Fog Creek has increased the revenue more than releasing a new version with more features. When a new version came out with new features, there was a sudden, undeniable, substantial, and permanent increase in revenue.

It is fine to use the term “simplicity” to refer to a product as meaning that the user model corresponds closely to the program model, so the product is easy to use. More, it is fine to use the term “simplicity” to refer to a product with a spare, clean visual appearance. However, if you think simplicity means “not very many features” or “does one thing and does it well,” you can’t go far with a product that deliberately leaves features out.
