In my opinion Encyclopedias should be the best of human being, compiling true knowledge and neutral information in order to improve our common destiny, culture, as human wherever we live, whoever we are. However and very unfortunately, Wikipedia is prone to lobbies promoting ideas (English, religious - Abrahamous religions and the most sectarians one, I won't comment...) over other. This way, Wikipedia is loosing all its neutrality and quality of Encyclopedia. As long documents promote ideologies rather than knowledge, for me it is not an universal Encyclopedia but rather a site of opinion, which, unfortunately Wikipedia is. The only luck of Wikipedia is that scientific/students are contributing to the site, giving interesting introduction about specific field. Take books or scientific articles and read rather than consulting Wikipedia is my advice. Very sad to have donate $ to this opinion site which is note an encyclopedia.
