Review of Wikipedia / Mediawiki

Summary

On the whole these web pages tend to be screen reader accessible and navigable with a keyboard. The registration may need an e-mail to the administrator. It should be noted that pages edited by the public are not necessarily very reader friendly as they have large amounts of text often with random links that when taken independently of the text may appear illogical. Depending on the user, tables and diagrams that are added may not always be accessible.
