If the site were more user-friendly, it would be easier to use for people who don't understand the initial complexities of Wikipedia. One of the contributors on that page wrote against a redesign because they don't want to have to re-learn how to use the site, insinuating that the initial learning curve was rough for someone who is an editor, not a web person.

The redesign should include better promotion for the site/make people aware of the contribution process just as much as it should focus on the content management and discussion portions.
