Blogger Definition

I was looking for information about blogging, bloggers and blogsphere (or "blogosphere") in the internet and found some pretty discouraging terms.

Urban Dictionary defines a blog in the following way:

"1. n.

Short for weblog.
A meandering, blatantly uninteresting online diary that gives the author the illusion that people are interested in their stupid, pathetic life. Consists of such riveting entries as "homework sucks" and "I slept until noon today." "

In the same way a blogger is defined as:

1. Blogger
"Term used to describe anyone with enough time or narcissism to document every tedious bit of minutia filling their uneventful lives. Possibly the most annoying thing about bloggers is the sense of self-importance they get after even the most modest of publicity. Sometimes it takes as little as a referral on a more popular blogger's website to set the lesser blogger's ego into orbit." 

And last but not least discouraging the term "Blogsphere" is defined as:

1. blogosphere

"A tragedy.
..........

The "blogosphere" is the new buzz word that has replaced "information super highway." It's what idiots like to call a collection of "blogs," otherwise known as a tragedy."

If you follow the links to that website, you will find many more demeaning adjectives about this new social media phenomenon. Could so many people be wrong, idiots or selfish? Or most of these qualifications could be applied to the same people that blatantly disrespect others?

Evidently, human beings that are capable of speak in such way about other individuals, speak a lot worse about themselves.

I would like to know what other people think about these opinions, any comments will be welcome.
