Saw an announcement from Zack Rosen about his sweet aggregator of progressive blogs and lists, Progressive Pipes. Zack’s the guy behind Deanspace, which powered much of the local organizing online for Dean. is wonderfully streamlined and user-friendly. It’s also wicked fast. Feels much faster and easier to get around than Feedster, which I also basically like. Ppipes is created in Drupal, which may be the best-of-breed * tool for this kind of aggregation and communication work.
Keep your eye on Zack and CivicSpace Labs. I think we can expect great things.
