(n.) - Someone who posts on blogs and social networks just to spin other people's more substantial and professional news reports and ideas.
"You know, the blogosphere is now full of so many people who set themselves up as a news karaoke artist, when in fact all they are doing is spinning someone else's commentary. Singing someone else's song. I hate what the Internet is becoming!"
