A blog is a discussion or informational site found on the internet and is made up of posts or entries usually displayed in reverse chronological order where the newest bit of information or thought appears at the top. Usually the information on a blog is that of a single person or that of many people on one subject. A typical blog combines images, text, and links to other blogs, web sites, or other media related to the topic. Chances are, that no matter your interest, there is a blog out there for it.
A Wiki is a lot like a blog but its content is created without any defined owner or leader. Wiki's also do not have an implied format allowing the outline or configuration to develop to the needs of the users. The best know wiki is of course Wikipedia but there are many other types and uses for wiki software such as think tanks, a corporation’s intranet, knowledge management or note taking.
Wiki's are a great way to share information and gain knowledge and the information of others. Anyone can start a wiki and anyone can easily edit their own or other wikis that have not been locked. Obviously the up side of such a web site is the ability to get information on a subject from people all over the world but the down side is that you never know when someone is going to give bad information unknowingly or on purpose.
My opinion of Wiki's have not changed. I have been using the Wikipedia site for years for research and my interests in computers, networking, and tattooing.
