Is the information on Wikipedia really credible?

I look at Wikipedia all the time when there is something that I want to be informed about. It's a tool that I use to arm myself with knowledge about virtually anything there is. But I've heard that anyone can be the editors of what is posted there, therefore some of the information may not be believable. So the question is this. In your opinion, is the information found on Wikipedia reliable?
Is the information on Wikipedia really credible?
Not 100% credible but good enough to start your research. You have to verify the stuff in Wikipedia with other sources.

It's pretty reliable, though not 100%. However, for truly objective information it's a reasonable place to start your research.
Reply:Although Wikipedia is good for general information it is not a reliable source. Anyone can post to it and even though they try to remove information that can not be substantiated, they are not able to get to everything. My advice is to use it to find links to more reliable sources.
Reply:With Wikipedia you have to know what you are looking at, information that can at any time be changed by anyone who has access to the Internet. On that level, no I would not consider Wikipedia to be reliable. On the other hand, Wikipedia is really good about letting their users know if information has been provided without a sufficient citing. I think that Wikipedia is a great place to start looking for information and to get a general idea about a topic, but if you want more detailed information, I would suggest starting with the citations at the bottom of each pager. These are where the information is pulled from and may be more reliable than the information on the Wikipedia page that can be changed at any time.
