Best of Wikipedia is that it has even the most obscure subjects explored in depth. If you need to understand something that a conventional dictionary misses then Wikipedia is the place to look. Wikipedia is a good example of the value of the internet. Many of the definitions have resulted from a collaboration of experts. The resulting information is the most current and inclusive data to date. This site is very educational. If we let the net alone great thing can and will happen. Dove Medical Press is an example of a thoroughly defined topic in Wikipedia. Let the system work for you.
