I’m working on a story about how social networks like Facebook and MySpace may be affecting yearbook sales at area schools. In school districts around the country, yearbook sales are dipping. In Houston, interest in yearbooks has gone the way of the DoDo. In Eudora, some students are opting for video yearbooks.At Kansas University, the heart of Facebook country, the university last year contracted with a Web site called e-yearbook.com to produce Web versions of past yearbooks.That’s not totally surprising to me, given the greater importance yearbooks have at high school. For one reason or another, my college neglected to send me any notice about purchasing yearbooks, or getting yearbook photos taken. But I’ve always been a sucker for the hard copy. Heck, I’m a newspaper reporter. With the vast array of social networks out there, are yearbooks obsolete?
