Steve Radick has written a nice post (Government Social Media Use – “In Addition To”, Not “In Lieu of”) that’s relevant here.

Excerpt: “…it’s about more than just identifying non-digital means to reach out those without broadband access – it’s about providing a variety of means, both online and off, for everyone…Government use of social media should be integrated with the communications and public affairs departments. Very few internet users rely solely on government social media sites – in fact, those who use government social media sites are more likely to also use other means, both online and off, to communicate with their government as well.”
