Blogs...Are They Really Useful?

The excerpt clearly states how blogs are beneficial for our lives, their topics and the way they influence and contribute to our technological world.

The author is showing how blogs have changed people’s lives and their approach to communication. This has been possible due to its improvements. It is out of reach to keep track of all of them or even make a book out of them.

I infer that the author is approving and encouraging the use of blogs by informing the reader  their use and how they work. 

"Blogs are fast" "There are political blogs, confessional blogs etc. (First paragraph)” “One of the surest ways to hoist your blog to the top of the charts is to bring down a big-time politician or journalist. (Last paragraph)”

Personally I think that even if blogs are very useful, they are replacing books and ways of communication that have been fundamental for human civilization. I think that blogs would soon replace something that was once important and useful for our lives: books, newspapers etc. Blogs will soon extinguish the means of communication that made part, and created in a way our history.
