I was just over at Little Green Footballs, and I see they now have links under each of their front page entries that people can use to recommend their stories to news-sharing sites such as Digg and Deli.cio.us. This will result in those entries potentially getting a wide readership beyond the LGF site as well.
My suggestion is that Daily Kos do this too for its front-page posts. Other sites you might want to provide buttons for include Newsvine, NowPublic, and Reddit. Media-sharing sites are becoming extremely popular, and by not jumping on this bandwagon sooner rather than later, you risk losing ground to the right-wing blogosphere.
I suppose I could have made this suggestion as a comment in an open thread. However, I'm making a diary out of it, as I'd like to encourage other dKos denizens to suggest other media/news-sharing sites they think it would be a good idea to provide links to.
