Last week, David Mihm noted that Steve Espinosa had reported seeing Twitter profiles showing up as local business citations. In doing some local listing research for another post, I came across not only examples of Twitter as a citation, but Facebook and MySpace as well. I hadn’t seen either of these mentioned as general sources of citations, so I thought I would make a note of it. It didn’t take long to find examples of a restaurant’s official Twitter page listed as a citation or a customer’s tweet as a citation. 
That same restaurant in the first link is also credited with a citation for their Facebook page. I was curious as to whether mentions of a business on other Facebook and MySpace pages were also being credited as citations along with their official pages, and wouldn’t you know it, they are.
It will be interesting to see the speed with which businesses are credited citations from these sources and their overall value compared to other accepted citation sources.
