KANYE RAILS AGAINST TWITTER: Plus, artist posts new Rihanna/Lady GaGa song on blog. Does it take a swipe at Chris Brown?

       The singer teams with Lady GaGa for a new song called "Silly Boy," which finds Rihanna saying in part: "You had a good girl that's a keeper… You had a good girl, but didn’t know how to treat her."  [Scroll down for song and lyrics: http://www.youtube.com/watch?v=fLSIXiUefZU]          

       The demo track was first posted on West's blog, as is a new rant in which the rapper lashes out against Twitter, the microblogging service that allows folks to communicate with followers 140 characters at a time.       

       In all caps – a.k.a. shouting – West says he's upset that someone is tweeting under his name. Also, he says he is too busy "being creative" to use the popular service.      

      Here is his posting, verbatim:

“DON’T HAVE A F****** TWITTER… WHY WOULD I USE TWITTER??? I ONLY BLOG 5 PERCENT OF WHAT I’M UP TO IN THE FIRST PLACE. I’M ACTUALLY SLOW DELIVERING CONTENT BECAUSE I’M TOO BUSY ACTUALLY BUSY BEING CREATIVE MOST OF THE TIME AND IF I’M NOT AND I’M JUST LAYING ON A BEACH I WOULDN’T TELL THE WORLD. EVERYTHING THAT TWITTER OFFERS I NEED LESS OF. THE PEOPLE AT TWITTER KNOW I DON’T HAVE A F****** TWITTER SO FOR THEM TO ALLOW SOMEONE TO POSE AS ME AND ACCUMULATE OVER A MILLION NAMES IS IRRESPONSIBLE AND DECEITFUL TO THERE FAITHFUL USERS. REPEAT… THE HEADS OF TWITTER KNEW I DIDN’T HAVE A TWITTER AND THEY HAVE TO KNOW WHICH ACCOUNTS HAVE HIGH ACTIVITY ON THEM. IT’S A F****** FARCE AND IT MAKES ME QUESTION WHAT OTHER SO CALLED CELEBRITY TWITTERS ARE ACTUALLY REAL OR FAKE. HEY TWITTER, TAKE THE SO CALLED KANYE WEST TWITTER DOWN NOW …. WHY? … BECAUSE MY CAPS LOCK KEY IS LOUD!!!!!!!!!”
