What is meant by blogging?

[Earner]

Blogging is the act of writing and publishing material on various Internet channels usually written in the form of articles, stories, or guides on a specific niche or subject. Blogging can be compared to running an online diary that gives an author a sort of a license to share thoughts, knowledge, or even experiences with his or her readers. Blogs can grow into avenues of educating, entertaining, or even influencing people. Some do it as a hobby, while for others it is their business.
