I want my MTV (on Twitter) - MTV crowns 1st Twitter Jockey

In an effort to embrace social media and create a two-way conversation with their audience, MTV has announced its first TJ or Twitter Jockey. The Wall Street Journal reports that Gabi Gregg, a 23-year-old fashion blogger from Detroit, became the network's first ever personality dedicated to social media. Sean Moran, executive vice president of sales and integrated marketing for MTV, VH1 and LOGO said, "Gabi is really going to be the eyes and ears of our audience. She will be their voice."

What do you make of the move by MTV to create a post solely for Twitter? Do you think that this move will help to extend the life of Twitter? What does this mean for other social networks who compete for MTV's target demographic?

We'd like to hear your thoughts.
