This looks like a very cool service that focuses on generating a "newspaper" from the links and stories in a twitter feed and from the feeds of those that follow a feed. It seems like it could have a great potential as a single update on a network of activitity. For groups working on issues this would work well if.
a. Main source (twitter account) links to the daily clips, actions and videos on an issue.
b. The main source follows all the members in the coalition and regularly retweets their news reports and actions.
c. The main source only approves followers that are in the coalition. (can we even do that anymore?)
The resulting "paper" would be tight and focused on the issues related to the campaign. With Google ads (grants) the calls to action and focusing on retweeting the videos the page could becomevery useful in coalition work. Just a few small tweaks (allogn others to embed sections, or adding navigation wrapping around the page and it would be a very robust hub for a coalition.
