Side note regarding Wikipedia - which I have donated to since it's beginning....
It is an excellent open source information resource that takes the responsibility of being reliable very seriously. If you've ever tried to contribute to or edit a subject entry there - you'll find that there is a system in place which facilitates the end goal of reliability. Nothing is perfect and nothing ever will be. But it is neither true or accurate to claim that Wikipedia is an unreliable source. It is, in fact, an incredibly reliable source. This is not an opinion. It is verifiably true. Not to mention that much of the subject matter there is not the kind of thing that you have an "opinion" about. For instance - the entry on the subject "Algebra". Like a lot of subjects - there's not much room for opinion about algebra.
