Blogger blog to much!!

The whole purpose of blogging is to write about some issue that others might care about, but think about it. Most blogs do not have any concrete evidence. The writers of the blog just want to complain about one thing or another. Issues that may be important to some but not to others, or in most cases the issues are argument. I think sometimes the writer of the blog just wants to start an argument the only difference is that the writer thinks they can win their point while their opponents think the writer is a moron and can not discuss the issue. So that leaves the question why blog? Some blog because their is nothing else to do while others blog because that is a part of their life, and in some very few cases blogger blog because it an assignment. But either why what you have to think about, Is blogging really worth wasting your short life time doing?
