While WordPress (as well as the other CMS) is commonly used for blogging, it can do MUCH more, it can be setup as a mailing list, online discussion forums, media gallery, online store, or a news site with articles pulled in from other sources, or local
content. Or you can set it up to be a combination of the above.
You can set it up so that other people have rights to publish articles, or can upload them for your editing/approval, etc.
My opinions are barely worth the paper they are written on here, but hopefully they can spark some new ideas, or at least a different train of thought
