Most people are led to believe the WordPress is just a blogging platform, but it is not. It is more than that. Some sites do not even have to have a blog. WordPress can create static pages. With the code snippets, lovingly called plugins, WordPress has become a very flexible script.
One site that shows how flexible WordPress can be, is WPVote. It is a Digg-like site geared to articles dealing with WordPress. If you write articles about WordPress, then you can definitely submit it there. However, in order to submit, you have to sign up so this site is trying to eliminate the spam that you usually see on larger social bookmarking websites. You can even vote.
Recently I submitted an article that I guest wrote on WPThoughts called Five Helpful Plugins For Site Navigation.
