Conservapedia
Overview
Conservapedia is a web site purporting to be a "pro-American, pro-Christian" alternative to Wikipedia. It uses the free, open-source MediaWiki software developed by the MediaWiki Foundation for Wikipedia.
The site appears to be owned and operated by Andrew Schlafly on behalf of the ultra-conservative Eagle Forum organization led by his mother, Phyllis Schlafly.
Unfortunately, due to subtly satirical posting by those opposed to Conservapedia's mission (vandalism), it is often difficult to tell which articles are genuine and which have been written so as to exaggerate conservative points of view (or represent only the most extreme of such).
As of 2007-02-25, editing is closed (you have to log in to edit, and the "log in/create account" page is log-in only), probably due to the vandalism; blog comments on 2007-02-21 indicate that new user registration was recently available. It is not known at present what the official reason was for closing down log-ins, nor whether Conservapedia hopes to be able to re-open them.
