Definition of Rating System:
One of the most important outcomes of the Web 2.0 Movement has been the idea of "moving beyond" the traditional billboard style, informational website. While sometimes an authoritative, informational website is precisely what one needs, it is important to think of other modes of interaction when planning to utlize information technology in your Company or Program. Different participatory medias are appropriate depending on how much interaction you want with "the world," your members, and your administration. Read Accessibility and Write Accessibility are two factors that greatly influence this decision. Read Accessibility is how "open" the information on the site is, and who exactly can see the data. Write Accessibilty involves how collaborative the site is and how much a user can add and edit.

Includes:
log-in options, partial visibility, adding major content, adding comments.

Excludes:
Write Accessibility for people with disabilities. See http://www.w3.org/TR/WAI-WEBCONTENT/ for information on how to make your sites more accessible in this manner. Also does not include the technical expertise needed to add content.
