WHO BLOGS?

eMarketer has release a report on the demographics of US bloggers.

Nearly 70 percent are white, 20 percent Hispanic, 12 percent African-American, and just under 4 percent Asia. They average 37.6 years of age, 14.3 years of education (that is, 2 years of college), and income above US$55,800. (Based on a survey of people 18 years of age or older "who regularly or occasionally write in a blog."

They predict the following:
2008: 25.2 million bloggers, 94.1 million blog readers (50 percent of Internet users)
2009: 28 million bloggers, 104.7 million readers (54 percent)
2010: 30.9 million bloggers, 116.1 million readers (58 percent)
2011: 32.8 million bloggers, 135.6 million readers (64 percent)
2012: 34.7 million bloggers, 145.3 million readers (67 percent)

I wonder what the comparable numbers for librarians would be? Does anyone know of any research in this area?
