Firstly it is important to understand the differnce between a wiki and a blog.Wikipedia defines a blog as "a type of website that is usually maintained by an individual with regular entries of commentary and description of events".I would add to that and say, a blog usually contains subjective information.Some blogs are dedicated to expert advice but most are owned by individuals expressing there personal opinions.Blogs can only be edited by the blogs owner and no outside sources can add or edit information.Thats were the differnce between a wiki and a blog lies.A wiki as defined by wekipidia" is a page or collection of web pages designed to enable anyone who accesses it to contribute or modify content using a simplified markup language.A wiki does not have one owner but has many owners,editors,and contributors.
Each of these sources of information has its advantages and disadvantages.A blog gives people the opportunity to express there personal opinions,give people advice,report developing news stories,and let an endless amount of people have access to that information.Since no one can edit a blog aside from its owner a blogs credibitly can be quistioned.In contrast a wiki can be edited by anyone creating information based on many different perspective.That type of information is richer and more in depth that it would be in a blog.On the flip side giving anyone the ability to edit the information can create the loss of valuable information and create a total mayhem.
A great idea I came up with for a wiki is one that focuses on addictions.It will be divided into many sub sections each dedicated to one type of addiction.It will give addicts the opportunity to share there personal experiences and help them support one naother.In addition it will have a whole section dedicated to expert advice that will give the addicts help to medical advice.
Its amazing how wikis and blogs have revolutionized the way information is accessed and exchanged.I wonderd whats next???
