The Brown (2001) article especially pointed out that sometimes the characteristics of the wireframe that make them useful are considered challenges or weaknesses. Wireframes are a bare bones view of what content will look like on a page. Their abstraction should allow those using them to interact with them more; to be able to see the page as a set of elements that can be moved and changed based on the needs of the site and its users. The article also points out another challenge: wireframes don’t demonstrate the interactivity of a live site and thus might not give the user realistic feel of the site.
Just like with cartoons, the more abstract a representation, the more the viewer can project their own ideas and personalities onto the design. For the purpose of wireframes (to present concepts, consider logic of the page, and provide an easy setting to manipulate and change the design) the minimalist view is in my opinion the best. You don’t want those trying to decide the order and structure of a site to get caught up in how the actual content looks on a page. They will begin focusing on aesthetics and functionality when the wireframe becomes too realistic. Just as with cartoons, wireframes should provide a framework for creativity without bounds.
