Future of blogs appears bright

From Ed Cone, via Steve Rubel, through Shel Israel, we find that Charlene Li published a new study of blog use and discovered that a quarter of Generation Y reads blogs, which is twice as much as Generation X and three times as much as Boomers (which generation was Generation F and, once the Generation Z of my kids grows up, will there be another generation after them at all, or do we start using the Greek alphabet instead?).
MySpace is for highschoolers. Facebook is for college students (who tolerate, for now, a small number of highschoolers, grad students, faculty and staff, but may leave in a stampedo if/when Facebook lets non-“edu” addresses in). So, what kinds of blogs do they read/write? Were MySpace blogs, Facebook Notes, MSNSpaces, AOLblogs, Xanga and LiveJournals counted in the study?
Joe McCarthy takes a long hard look at a whole series of polls and studies on blog use by various age groups.
Out of millions of Gen-Y-ers reading and writing blogs, I hope at least some cover science-related topics sometimes, or come to ScienceBlogs to interact with us. How many of my readers are Gen Y?
