What is a Blog?

According to www.britannica.com (1), a blog is an "online journal where an individual, group, or corporation presents a record of activities, thoughts, or beliefs".
www. webopedia.com (2) says that it is "short of Web Log [...], a Web page that serves as a publicly accessible personal journal for an individual. Tipically updated daily, blogs often reflect the personality of the author".
Nevertheless, on the website www.dailyblogtips.com (3) we can read that it doesn't have to be a personal blog, there are several different types.

But, apart from personal ones, how many types of blogs are there? Here there are the main types according to Wikipedia (5):
      1.- Collaborative blogs or group blobs: a blog where more than an author can writte. The vast majority of them are based around a single theme.
     2.- Microblogging: we do that when we post small pieces of digital content, like videos, links,... on the Internet in order to being in touch with friends or sharing useful resources. We can do that through platforms like Facebook, Twitter, Tumblr, etc.
     3.- Corporate and organizational blogs: these blogs have the aim of improving the communication between the members of a company and being known externally.
     4.- Aggregated blogs: these blogs are made by the aggregation of different ideas. They allow us to understand different points of view on the same issue.
     5.- By genre: we can find blogs that focuses on a single subject, like fashion, books, animal, health, cooking or education.
     6.- By media type: it is a classification by the content, for instance, if they comprising videos are called vlog or if they comprising links are called a linklog.
     7.- By device: referring to the type of device for which it has been designed.
     8.- Reverse blog: blogs are usually made by a single blogger or the association of several. However, this kind of blogs are composed by its users.

But, what type of blogs are the educational ones?
As I said before, educational blogs are in the fifth group and Wikipedia (5) says that  an edublog "is a blog created for education purposes. Edublogs archive and support student and teacher learning by facilitating reflection, questioning by self and others, collaboration and by providing contexts for engaging in higher-order thinking [...]. Blogs can be useful tools for sharing information and tips among co-workers, providing information for students, or keeping in contact with parents".
Therefore, by using the blog, our students can achieve higher and better goals, and learn who to use their mobiles or computers to learn, not only to enjoy or chat with friends.
The authors of the guide Innovation in Learning and Teaching Interaction, Reflection and IT (6) assert that, through the use of edublogs, students can get to develop their oral and written communication skill and to be able to contribute to an online project workspace.

To put things in a nutshell, I absolutelly agree with John Saddington (4) insomuch as I believe that, nowadays, a blog can be whatever you want, a learning tool, a way to express your thoughts or a place to meet fasion trends.

 I am going to use it as a learning tool. 
What are you going to do?
