We are all trying to create something that will be used and the path to this success is designing for a particular group of people. It isn't just about solving a particular PROBLEM or coming up with a particular IDEA.
Only when you match a PROBLEM with a PERSON or an IDEA with a PERSON are you at the place where you can start making design decisions.
There's always more than one way to do something and what validates one choice over the other is if it's the best choice for someone specific (this often means a group of someones)
This example is super simple (maybe too simple) but it expressed my point.
This site has a main navigation just like most sites because like most sites it needs to solve the problem of getting peeps to some major chunks of content so they may interact with it. They also have an idea (to share information about the company)....
but where is the Navigation? If this was a store or a bank site we would have a problem. But it isn't a store or bank. It's a creative company that is hoping to attract companies who are ready to engage the creative process to improve their businesses.
These people don't have the same needs. There is no need for a persistent, in your face navigation. They will enjoy the page and then when ready roll over the little box, expose the navigation and choose another topic to explore. They are willing to discover and uncover (woo, i like that)
