Bloggers are people who operate a Weblog for private or business reasons and publish articles called "Posts" there at regular intervals. Posts by bloggers are usually characterized by the fact that they reflect subjective views. This subjectivity can refer to a person alone, to a group or even to an entire brand or Corporate Identity. A Blogger can also be referred to as a Linkerati if he or she reaches a large number of other people with his or her contributions due to his or her personality or Position.
As far as topics are concerned, bloggers are not restricted, because there is no topic that cannot be blogged about. For this reason, there are fashion bloggers, Auto-bloggers, political bloggers, etc., that Some bloggers are coming together to community Blogs, where multiple editors can post to a common theme.
Private vs. Commercial
The number of bloggers living in Germany cannot be accurately estimated. There is some talk of more than 100,000 people regularly blogging. However, the number of Blogs overall is rather declining,as is also shown in the ARD / ZDF Online Study 2013. one reason for this trend is certainly that Blogs in Germany are less integrated into the Social Web than in Anglo-Saxon countries or the USA.
