According to official numbers provided by Nielsen, traffic to Twitter.com was down a dramatic 27.8% between September and October 2009, falling to 18.9 million unique visitors. While the drop of 27.8% to the actual website does not take into account the growing number of Twitter followers who use phone based apps like Twitterific and therefore bypass going to the site, the steep decline has raised eyebrows with marketers across all industries, especially music.

While traditional consumer packaged goods companies have failed to find the right way to use Twitter, most accounts are inactive or just stay active during promotional periods, hip-hop artists and their fans have flocked to the 140 words or less as a means for artists to stay connected to their fans and fans to feel like they are part of the artists’ lives. Want to be a major hip-hop artist? Well then you gotta get yourself a Twitter account…much like you had to have yourself a MySpace a couple years back. But all is not well in Twitter land for the hip-hop nation.

The Twitter backlash has already started with prominent well-known artists like Kid Cudi flat out rejecting the Tweetness. “I will NEVER get back on twitter or facebook. im gettin my blog back together and that will be the only way to stay connected with me” he recently stated. And other artists like Jay-Z tend to stay away just because of the privacy issues. “I watch it through everyone that’s around me; so I’m like a Twitter voyeur or something,” stated Hova earlier in the year.

But the balance of hip-hop support for Twitter remains a delicate one as it has almost reached the point of saturation and copy-cat marketing has plagued the industry. Every artist now follows the same Twitter strategy: release their album art, teaser trailer for an upcoming video, then the actual video via Twitter. More popular artists are even using label interns to post as them to keep fans coming back. This so called strategy is becoming such a predictable pattern that definitely does get the word out but how much interest does it really generate to turn casual fans into actual consumers?

So what is the future for hip-hop and Twitter? Does Kid Cudi leaving Twitter open the floodgates for other artists to follow suit? Or is he shooting himself in the foot by alienating the potential 18.9 million Twitter viewers out there?
