Word Web App is a slimmed down version of Microsoft Word 2010, as are the rest of the Office Web Apps. Word Web App is automatically updated by the folks at Microsoft, so as and when new features arise, these will appear seamlessly.
Not all functionality appears, but the very basic and only necessary features are built-in to the Office Web Apps. These will include styling, formatting, formulas in the case of Excel, and picture management.
As a site administrator, you are able to create custom pages without having to concern yourself with basic HTML or advanced coding.
