Here's a nifty website I came across recently. DocStoc allows you to upload documents you've created. You can not only store your stuff there, you can embed your documents in webpages you create in message boards, wikis, or...oh...say...blogs so others can view or download them.
You have the option of making your documents public or private, and you can search through their public files for documents you might want to use yourself. This is an ideal place for teachers and students alike to publish their works online for class.
Here's an example of how they're embedded using a rubric I created:
