And, if anyone wants to chime in on something that was briefly mentioned in this original question - How to handle the time consuming nature of citizen journalists.  
I have been hit with a few of these in my district and they are taking up the majority of my "media relations" time.  I want to treat all media the same, but I think this could pose a huge staffing issue for schools - this could easily become a major part of a PR person's time and with so many of us being one-person departments, how will we manage?
 

We have two examples of this in our community.  One is a stab at citizen journalism by a major newspaper (the Chicago Tribune) called TribLocal and the other is a local website (www.gazebonews.com) that has gone from a blog to what I now consider a major news source that I treat just like any other traditional media.
One of the biggest issues hasn't been the writing or editorial nature of the blog (which has been for the most part really good) but the allowance unnamed comments.  They can be downright vicious.  Oddly they can turn on each other too.  But they present a real risk the commenter's view/argument becomes the story.  These comments can become a PR nightmare.
The TribLocal citizen journalism experiment has been a sleeper around here.  Don't know that it will ever become a player. 
In the end, I still utilize the traditional media more often because of that.  As long as the traditional news media stays around!
