See online content in services. Developing online content is the job of trained writers and designers. It is not a task for a Webmaster or committee. Content should be clear, persuasive and in logical chunks. This requires creative and presentation skills.
Content includes sound, data, text, still and animated graphics.
This is not an easy answer. Some will say the Web, but that might not be true. Commercial online providers such as America OnLine and CompuServe provide outlets that might be better suited for your target audience. Before you make a decision where to post your online content, do an online audit. Revise online content regularly.
