The citizen journalism aspect that might interest you is that you can use the application to upload a photo or video directly to CNN via your iPhone. If you are a participant in the CNN iReport community this could be a cool thing to have.
Please remember that you will pay for any data charges involved in uploading content. Those of you on the ka-ching side of your limited data plans need to be especially careful.
You might want to examine the terms of service and what rights and financial compensation you potentially will give up should you use the application.
