A critical evaluation of Wikipedia

Wikipedia is also called a Free Encyclopedia. That terminology is correct. The basic problem is many people contribute to Wikipedia, all with good intentions, but the major result is that many articles suffer a common goal. Some look like a quilt.

Anyone can modify each article anonymous. I do not understand why this is possible. Why not use your full name ?

The following articles are discussed in alphabetical order:

MIT Technology Review The decline of Wikipedia By Tom Simonite on October 22, 2013. With 312 Comments

Reflection

Many articles start with a lack of definition or the defintion is not clear. When you do that with may contributors to write a good conherent article, is very difficult. The overall result for certain articles is mediocre.

Suppose for a certain subject there is an issue which raises doubts with the main opinion, what will happen? If one side wants to expresses this new opinion the other side will modify it and so on. Finally one side will give up. That means it becomes very difficult to express a different opinion and or to improve science from a different angle.
Possible solutions are: to express both opinions, to have a moderator or to have an editor?
