"Amazon.com takes the friction out of grass roots contributions to [US] Presidential candidates. A 1-Click payment is the easiest way to make a contribution -- from $5 to $200."
The most remarkable thing about this Presidential campaign so far has been the impact of eMedia: WebLogs, Internet campaigns, home grown videos (that Dean "yeeagghhh" moment has single-handedly spawned dozens of rap tracks, flash movies etc), 1-click donations, text messaging, etc.
The impact of technology on social networks is part of this movement. I suspect that Politics is moving into the world of aggregation; not so much "micro-content" as "micro-viewpoint".
Politicians will need to find the RSS feed for our views...
