Pew: “Blogging has declined in popularity among both teens and young adults since 2006. Blog commenting has also dropped among teens. … While blogging among adults as a whole has remained steady, the prevalence of blogging within specific age groups has changed dramatically in recent years. Specifically, a sharp decline in blogging by young adults has been tempered by a corresponding increase in blogging among older adults. … Both teen and adult use of social networking sites has risen significantly, yet there are shifts and some drops in the proportion of teens using several social networking site features. … Facebook is currently the most commonly-used online social network among adults. Among adult profile owners 73% have a profile on Facebook, 48% have a profile on MySpace and 14% have a LinkedIn profile. – The specific sites on which young adults maintain their profiles are different from those used by older adults: Young profile owners are much more likely to maintain a profile on MySpace (66% of young profile owners do so, compared with just 36% of those thirty and older) but less likely to have a profile on the professionally-oriented LinkedIn (7% vs. 19%). In contrast, adult profile owners under thirty and those thirty and older are equally likely to maintain a profile on Facebook (71% of young profile owners do so, compared with 75% of older profile owners). … Teens are not using Twitter in large numbers. While teens are bigger users of almost all other online applications, Twitter is an exception.”
