This is very interesting and new for me  to know that Wikipedia is based on the concept of open source and participatory journalism. I’ve always used to enter “wikipedia” in the search option of my Yahoo! in order to find the main well-known facts about somebody or something. I have never doubted the reliability of the information I looked through.

 For me,  I always find very useful information there, also I usually check the information through various other sites, connected to my topics. Thus, the credibility of the information from Wikipedia could not be doubted, though I should say that it would better use the main factual things from there, rather than opinions or information should be checked somewhere else. But nevertheless, it concerns all internet sources in general, which of course are still very doubtful.
