Just heard about this research data that was just released by GfK MRI in their Survey of The American Consumer.

So did you guess which website ereader owners are most likely to visit? (aside from mobileread of course

)
LinkedIN!
And also on the list, Twitter and Facebook. So this data suggests ereader owners are very likely to also visit social networking sites.
They also found that we were more like to have college degrees, earn over $100,000/year, and be between the ages of 35-44.
All in all, is anyone really surprised?
