A buzzword created to represent the overall bloging bloggity blog blog community. Often used by those who want to convince themselves that they are some sort of "internet professional", but instead come off as sounding completely ridiculous.
I cant believe there are people who still use the word blogosphere in sentences that are intended to sound intelligent.
Imagine a million lunatics wanderingthe streets mumbling to themselves. Write it all down and put it on the web. Congratulations, you've just created the blogosphere.
The "blogosphere" is the new buzz word that has replaced "informationsuper highway." It's what idiots like to call a collection of "blogs," otherwise known as a tragedy.
