If you go on to Wikipedia and spend a few hours or days viewing conservative people/events of note and liberal/democratic events of note there is a pretty disturbing bias on the way the information is presented to the reader and also the ability of the general public to revise or add to that information. For example a liberal supported Wikipedia reading will almost always allow you to edit but if that edit does not align with the opinion or view the the Wikipedia hierarchy you will end up in an EDIT WAR within minutes and then get suspended without ever being allowed to have a conversation about why your edit or addition is indeed factual. If you want to edit or add to a conservative person or event page those are almost always locked for editing with the excuse that they are trying to prevent vandalism or edit wars. It's really bad for anything related to politics or culturally sensitive matters.
For other topics of interest where subjective bias is not applicable it is okay but the bias regarding politics leaves me questioning the validity of anything related to history of countries and people of note as as well.
