Two Pew Internet Project surveys of teens and adults reveal a decline in blogging among teens and young adults and a modest rise among adults 30 and older. Even as blogging declines among those under 30, wireless connectivity continues to rise in this age group, as does social network use. Teens ages 12-17 do not use Twitter in large numbers, though high school-aged girls show the greatest enthusiasm for the application.
Blogging has declined in popularity among both teens and young adults since 2006. Blog commenting has also dropped among teens.
14% of online teens now say they blog, down from 28% of teen internet users in 2006.
By comparison, the prevalence of blogging within the overall adult internet population has remained steady in recent years. Pew Internet surveys since 2005 have consistently found that roughly one in ten online adults maintain a personal online journal or blog.
In December 2007, 24% of online 18-29 year olds reported blogging, compared with 7% of those thirty and older.
By 2009, just 15% of internet users ages 18-29 maintain a blog—a nine percentage point drop in two years. However, 11% of internet users ages thirty and older now maintain a personal blog.
73% of wired American teens now use social networking websites, a significant increase from previous surveys. Just over half of online teens (55%) used social networking sites in November 2006 and 65% did so in February 2008.
47% of online adults use social networking sites, up from 37% in November 2008.
Adults are increasingly fragmenting their social networking experience as a majority of those who use social networking sites – 52% – say they have two or more different profiles. That is up from 42% who had multiple profiles in May 2008.
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.
Teens are not using Twitter in large numbers. While teens are bigger users of almost all other online applications, Twitter is an exception.

8% of internet users ages 12-17 use Twitter.2 This makes Twitter as common among teens as visiting a virtual world, and far less common than sending or receiving text messages as
66% of teens do, or going online for news and political information, done by 62% of online teens.
Older teens are more likely to use Twitter than their younger counterparts; 10% of online teens ages 14-17 do so, compared with 5% of those ages 12-13.
High school age girls are particularly likely to use Twitter. Thirteen percent of online girls ages 14-17 use Twitter, compared with 7% of boys that age.
Roughly half of 18-29 year olds have accessed the internet wirelessly on a laptop (55%) or on a cell phone (55%), and about one quarter of 18-29 year-olds (28%) have accessed the internet wirelessly on another device such as an e-book reader or gaming device.
The impact of the mobile web can be seen in young adults’ computer choices. Two-thirds of 18-29 year olds (66%) own a laptop or netbook, while 53% own a desktop computer.
Young adults are the only age cohort for which laptop computers are more popular than desktops.
African Americans adults are the most active users of the mobile web, and their use is growing at a faster pace than mobile internet use among white or Hispanic adults.
Internet use is near-ubiquitous among teens and young adults. In the last decade, the young adult internet population has remained the most likely to go online.
93% of teens ages 12-17 go online, as do 93% of young adults ages 18-29. One quarter (74%) of all adults ages 18 and older go online.
Over the past ten years, teens and young adults have been consistently the two groups most likely to go online, even as the internet population has grown and even with documented larger increases in certain age cohorts (e.g. adults 65 and older).
Our survey of teens also tracked some core internet activities by those ages 12-17 and found:
+ 62% of online teens get news about current events and politics online.
+ 48% of wired teens have bought things online like books, clothing or music, up from 31% who had done so in 2000 when we first asked about this.
+ 31% of online teens get health, dieting or physical fitness information from the internet. And 17% of online teens report they use the internet to gather information about health topics that are hard to discuss with others such as drug use and sexual health topics.

Recently I have found myself cooing over visualisation maps (and heat maps) of health and well being resources. The content rich data is overlayed with mapping technologies, and some interesting themes and patterns are emerging.
A lot of the talk around social media in the last year has been around information overload. Social media has provided us with new and exciting ways to create content. But it has also meant learning new ways to manage and engage with social media tools. Are we teetering on the edge of an information overload precipice?
Information overload is a figment of your imagination. Or a failure of your filter. Or a symptom of your technological submissiveness. Depends on who you ask.
What if you had to sort through 3.5 million articles and social media posts a day and try to pull out the most relevant items for your organisation? What if you then had to cobble it all together into something readable for your top groups and executives in your organisation?
