Wellcome, if you want to leave a message, please do it in my Portuguese discussion page and If you do not speak Portuguese... at least try. We try :) This experience was illuminating and helped me a lot to understand the controversy, the lobby and the motivations behind the different Wiki projects. "another brick on the wall" i would say ...
As anyone can edit almost any article, it is of course possible for biased, out of date, or incorrect information to be posted to Wikipedia. Especially on April Fools' Day. However, because there are so many other people reading the articles and monitoring contributions using the Recent Changes page, incorrect information is usually corrected quickly. Thus, the overall accuracy of the encyclopedia is improving all the time as it attracts more and more contributors. You are encouraged to help by correcting articles, validating content, and providing useful references.
