You don't need Photoshop for silly pages with form elements. And that project is not "complex" just because it has a lot of data on it.

This article is trying to prove you can design a basic page without PS. Last time I checked every person with some brains can sketch something on a paper and then code it. The problems arise when you need multiple page types, layouts, various styles, and on top of this your team members don't all code in the same room. Try coding a sketch paper design with someone from the US and Australia at the same time. Try scanning and sending that paper and getting feedback that they don't know what your circle and squares mean. There's a reason why PS is useful, and it's not for the example portrayed in this article.

Downvote this! and then downvote your bragadacious, self-promotional post. Your comment tells me you haven't even read the original article.
