The 3 Clicks Rule. How many clicks should it take to reach your content? (@allyreeves)

I recently worked with a client that was very concerned about the “3 clicks rule”. 

You’ve likely heard of this before: the idea that a user is only willing to click three times before abandoning a site if they don’t see the item they are after. This thinking becomes troublesome when designing complex sites like libraries, large organizations or e-commerce: it can make clients nervous about answering to everyone’s needs (put it on the on the homepage!) and it can lead to suggestions of loading everything into a structure that cannot accommodate growth over time or that creates an overwhelming experience for users.
