A blog is nothing but a web log , traditionally used to write about ones personal feelings , thoughts and other personal issues.It is more or less like a personal diary.But , today the scenario has changed altogether.It is more of a private property.People express their opinions and feelings in it and then let others read it by sharing it with them.With the advent of blogging for money , it has gone to the extreme ends that people have started blogging as a profession , as a hobby and also as a means to make a living.That is how blogging has changed over the years.A couple of years ago , not many knew what actually blogging was.But now , everyone knows what a blog is and what all things are associated with it.
