There are several different, though similar, definitions of the word, “blog.”
The word “blog” is a contraction of the term “weblog” or “web log.”
The term actually originated from online diarists. Early web diaries (c. 1994) evolved into web journals, then web logs, and, today, blogs.
A blog is a type of website where material is published on some periodic basis in reverse chronological order through “entries” or posts. In other words, for readers, the most recent post comes first.
Though blogs are most commonly used for personal online journals, blogs are used in wide variety of ways. Types of blogs include business blogs, political blogs, news blog, travel blogs, fashion blogs, project blogs, education blogs, niche blogs, music blogs of all varieties, and much, much more.
Most bloggers are hobbyists motivated by self-expression and sharing expertise. Contrary to the common perception of bloggers being controversial, snide, sarcastic, or pompous, most bloggers feel that their blogging style is sincere, conversational, or expert.
While many hobby bloggers enjoy blogging and stick with it, most blogs actually die quite quickly. Other blogs die a slow death, with irregular, hit-and-miss posting, and then… nothing. Last year, I took a look back at the blogs I had been reading a year earlier. Less than a quarter of them were still active.
