A blog is short for a personal “weblog.” It usually has a single author. Sometimes can have multiple contributors. It is a public space where everyone can view and add comments on any post. Blogs can be very personal, unique in style and controlled by an individual. A blog is usually where an author shares their thoughts and ideas at that moment, so they are historical and relevant to people at a point in time.
A wiki is a website that allows multiple users to create, modify and organize web page content in a combining manner. Wikis are open so that people can combine and connect with other people within a circle of wiki users (Wikipedia on Wikis). In a wiki, there are managers that control the content (but there are different ways to do this (Cohen 2009). In our wiki, our instructor grades each participant individually and looks over the wiki.
I do not know how important it is that there be convergence of people through blogs and wikis. For example, I wonder if too many people can be convinced of wrong things (like fake news) in our networked world. So convergence of opinions and political beliefs is not always good.
But it seems like wikis are perfect for collaboration, since everyone is working together to create something in wikis (Locher 2008). They can be used to create documents, software and internet services. They are like open-source software and a type of crowd-sourcing. Wikis are great for people who want to create things for free and open to the public.
Maybe a new use for wikis could be education. For example, professors could collaborate to create a wiki for a course. The wiki will be like the textbook or lecture open for the public.
