How is all this information organised? On a traditional website, there tend to be two mechanisms for finding stuff: search and navigation menus. Traction has an excellent search engine, but it eschews menus in favour of tags. Menus are difficult to maintain: they require managers to make decisions about what hierarchical structure the menus should have, then take decisions about how to categorise incoming information. If something doesn’t fit the existing hierarchy, it tends to get forced into an inappropriate category. Tags on the other hand are simple text labels. A blog article can have as many tags as you like, and tags can be created by any user when they need them. You can use these tags to filter and search the blog, combining multiple tags to drill down to what you need. As more and more information is available to us digitally, hierarchical menus are going to become increasingly unwieldy: tags are one way of beginning to address this information overload.
