I would agree that the greater potential from candidate blogging is from community blogging (i.e. my.barackobama.com) and not so much from official paid candidate blogs. I've been wondering about something: How much danger is there really from opening up access to community blogging on a website like my.barackobama.com? I made the point in my post that Obama's website needs a recommended list, a blogroll, a full list of diaries --- all of these tools that other sites have used to great success in creating vibrant, engaged online communities.
These are supporters who will, independently of the candidate, magnify and spread their message throughout the country --- this is true even if the readers of these new blogs are no one outside of their family and friends. New people are draw to blogging through mainstream candidates than through establishment blogs that are perceived in the media as too far left or too far right.
Most of these newly-minted bloggers are very committed to the campaign, defensive about their candidate, happy to take tips from the campaign and spread its message. These community bloggers exchange tips and encouragement, coordinate responses to news articles and write letters to the editor (this is one of the biggest functions of my.barackobama.com that i've seen so far), exchange new arguments that could be useful while canvassing or phone-banking. There are clear benefits from the liveliness that such a website could produce. (DailyKos and MyDD have also proven that online communities can be pretty potent when it comes to generating fundraising too.) Such a community has the potential to revitalize democracy a little bit.
So what is the risk? For one, there's the possibility that a journalist could do a piece on the website and quote from community bloggers extensively as if they were surrogates for the campaign --- this doesn't actually seem that likely to happen. First, partly because the mainstream media still seems reluctant to quote these kinds of online sources. Second, other candidates have taken the plunge and haven't really suffered any consequences: Edwards has a blogroll and a recommended list, while Clinton's Hillaryhub.com highlights a list of blog posts on MyDD and DailyKos --- and to my knowledge not one has even been cited in a press piece (though Hillaryhub also seems to steer away from some of the more caustic Clinton supporters/bloggers on MyDD and it doesn't highlight community blogging on its own site.)
The bigger risk is another David Geffen moment . Racist/sexist/obscene comments posted on candidate blogs aren't really the problem, since the campaign has no problem deleting and repudiating them, though it is an interesting point that MyDD and DailyKos work partly because they have no compunction about banning users that cause trouble --- would political campaigns be as willing? The bigger problem is when candidates are called upon to repudiate statements from supporters critical of other candidates.
Opposition research teams will probably be scanning through the blogs. It would probably not be too hard to find a critical comment of the Clintons somewhere on my.barackobama.com, and, in this scenario, just to take an example, Obama would be challenged to reject the comment. (Geffen's "lying comes to them so easily" comes to mind.)
But besides just being uncomfortable, is there really any danger in this kind of situation? The David Geffen moment was a pretty tiny ripple in this campaign. No one not playing insider baseball would know who he is or why he matters. In the media coverage, it was more about judging the relative professionalism of the media veterans in both campaigns. Second, the campaign can just as readily say that they had nothing to do with the comment --- that it doesn't respresent their views, etc. Wouldn't that suffice? (Hm... I wonder if a rival campaign could actually call upon them, as site administrator, to delete the comment or ban the user...)
Anyway, sorry for the long comment. I'd be interested in your thoughts.
