I found this site while trying to update my portfolio site. This website helps designers go step by step in creating their site to promote their design skills. I know not everyone will want to be a freelance designer, but I think it is very important to have a site even for when you are looking for a job. By promoting yourself you show a sense of individualism and responsibility.
This site explains the importance of a few things that can make you or break you. A logo is one very important item to have on your site. It helps define you. I would recommend this site to someone that wants to build a simple site to help get some freelance work and promote themselves in the design world.
