Eric Eckl of Beaconfire Consulting recently released an interesting report titled "A Network of Networks: Email Lists, Nature Protection, and Pollution Control."

Eric explains, "The report reveals just how many people have formed spontaneous groups to engage in civic activitism, and what their behavior portends for the Web 2.0 world."

It's a must read for anyone interested in network advocacy. Through his own research of different environmental list servs, Eric generated this report which goes over the best practices of successful email list servs and why environmental groups need to take notice of new online communities such as Digg and Flickr.
