My main interest in Wikipedia is federal politics (Canada) and the institutions of Canadian government. Wikipedia can be a fantastic source of information, but it is important that the information presented is factual. Especially on political pages there is a a great potential for bias and abuse. Even "facts" can be stated out of context and present a slanted picture. Constant vigilance is required, otherwise there will be a total loss of credibility and you might as well remove all political pages!
