Older Online Users Taking Up Social Media Rapidly

A recent study by the Pew Internet and American Life Project has shed some light on how older Americans are using social networking and other sites on the Internet. It's known that the younger set are on Facebook constantly -- but which age group is watching more online video and showing huge gains in social networking?

In terms of regular social media usage, "millenials" aged 18-33 are still more likely to be engaged in social networking, video watching and online classifieds, but those aged 24-45 are more likely to use government sites or to seek financial information. 

The interesting statistics are that the usage amongst "older boomers" aged 55-64 has jumped from 9 to 43 percent between December 2008 and May 2010. Also, for those Americans over 74, online use went from 4 to 16 percent.

The story of the stats is that older Internet users are hopping online and interacting with the social web where as usage in the younger sets hasn't grown nearly as fast. These statistics are interesting to think about as you consider buying your parents or grandparents electronic toys this holiday season.

How is Twitter Utilized Going Into 2011?

Twitter is no doubt a popular and influential force in the social networking space. The service is simple, with 140 characters that users can utilize in any way they would like. But -- how has usage changed on the service between 2009 and 2010? A new study seeks to give us insight.

An interesting statistic from social media service Sysomos shows that users who created a Twitter profile before January 2009 now account for just 4.7% of the total Twitter population, meaning most users on Twitter are relatively new. Also, more than twice as many users in 2010 are putting information in their bio. Finally, we are following more folks on Twitter, with the number of users following more than 100 people increased three-fold to 21%.

Twitter is often a noisy environment and the statistics show that users are trying to get more out of the service by pouring more of their personality and personal lives into their tweets. As a Twitter user, I can attest to the service being more useful as you become more of a personality on the service. 

Blogging May Have Peaked

Blogging, once a major force in the social media movement, has seemed to peak in popularity and interest. As online users spend more being online, their engaging in activities such as watching videos, listening to music and reading the news. However, attention being paid to write blogs is on the decline amongst teens, according to Pew Internet and American Life Project.

Also, amongst Internet uses aged 18-33, blogging showed a slight decline. One bright spot for bloggers: amongst older generations, adult blogging is up over all from 11% in late 2008 to 14% 2010. It seems that with Facebook, Twitter and other real-time information options, long-form blogging has declined in popularity amongst younger internet users. One interesting note: millennials appear to love to "read blog" as they've ranked reading them higher than any other age group.

What about you -- if you were a blogger a few years ago, are you still writing in this form? Or have sites such as Twitter and Facebook drawn your blogging energy away? Let's discuss below in the comments!

TripAdvisor and Facebook Team Up To Offer Travel Advice

As the holiday travel season advances, we're constantly looking for advice and pointers regarding travel.  Whether it's where to stay, where to go on daytrips or other considerations, there's nothing like a close friend or family member to offer first hand advice to make your trip smooth and easy.

This is the spirit behind a new partnership between popular travel review site TripAdvisor and Facebook. With a new integration, Facebook users can utilize a TripAdvisor app to show friends' experiences in locales across the world. By utilizing a map, push-pins appear where a Facebook friend has left a comment or review on a hotel, restaurant or other travel destination.

This is a good partnership as Facebook is a huge repository for our friends' and family updates and TripAdvisor is the world's largest travel site. By combining forces, travelers can get just the advice they want from folks they already know and trust.
