Wikipedia

Wikipedia is an encyclopedia that is developed by its visitors. Therefore sometimes the information that you see there is not absolutely correct. However in some degree it is helpful. The interesting point is that it is in over 40 different languages! It also covers current events. So its a source of news as well as an encyclopedia. You can also reflect your own views in the discussion section attached to every article. However I don't know who manages it. Since people could come and delete or destroy articles there must be someone to take care of changes that are made by people.
