One of Wikipedias founders is making an attempt to rectify some of the inbuilt weaknesses of an anonymously edited encyclopedia with a new project call Citizendium.
The idea is that each subject would be led by a scholar in the field. It would not suffer the same vandalism and would have less errors. In other words it would be a credible source rather than just a second hand information source.
One of Citizendiums example projects is the Crystal Palace. Take a look and see whether you think it more credible.
