Hillary releases video statement on Iraq

Earlier today Hillary released what her campaign says is the first in a series of web video statements.  Called Hillcasts, this one is on Iraq.  You can see it here

In this cycle political video is migrating from 30 second spots to the web and eventually to mobile phones.  It will be interesting to see what form these videos take.  On TV videos are 30 seconds.  The video Hillary released today is 3 minutes.  Is this a good length? For her site? For youtube? For mobile media? As a former television producer I am fascinated to see the creation of this new whole form of political communications - non TV video - one which is being embraced with great intensity in the early days of politics 2007.
