I built this in after talking with Britt about the idea for future Howard Dean sites to include rotating "volunteer statements" as part of the design.
That's funny, Zack and I were talking about something similar on AIM as part of the endorse module (but we kind of agreed to put it into something separate).
I think it's a dynamite idea myself. Just like how if you go to theonion.com, they have a featured personal ad; this will encourage people to put their stuff out there.
