viacom internet on the move

I've been monitoring Viacom's latest moves on the internet.  They are very interesting.  It appears that after losing out on MySpace they are finally executing on a new Internet strategy.  Yesterday, we learned about their investment in TagWorld, primarily for its web2.0 technology.  Today, they purchased RateMyProfessors.com.  In my opinion, this is a great acquisition.  One of the strengths of MySpace is its ability to address the needs of kids, teenagers.  Almost every student, whether you are in college or high school, does a little research about their teacher.  Who to take?  Are they a tough grader, or an easy A?  Which teacher is hot?
    The question is, how will this all integrate together?  Will we see URGE (MTV's music site), TagWorld tech, and RateMyProfessors come together under one meta-site?  At the very least, today shows that Viacom is heavily in the game.  I expect to hear about more purchases by MTVN soon.
