This is a very helpful and interesting graphic that appeared on Mashable.com recently, under the headline:  Are we too obsessed with Facebook?

One out of every 13 Earthlings and three out of four Americans is on Facebook, and one out of 26 signs into Facebook on a daily basis.

This terrific infographic is from SocialHype and OnlineSchools.org.  Take a look and let us know what you think about the Facebook phenomenon.

Twitter seems to be the social network of choice for Fortune 100 companies.  Their use of Twitter, as compared to Facebook and corporate blogs, varied but “76% of Fortune 100 companies that were using just one social media channel were using Twitter over Facebook and blogs” according to the study. 

A full 94% of these Fortune 100 companies use Twitter to distribute company news and 67% are now using Twitter for cusomter service functions.  As far as industrys are concerned, it’s probably not a big surprise that the Technology segment is the most active user of Twitter, led by Dell, IBM, Microsoft, Cisco and HP.  These companies tend to have several corporate Twitter accounts that they staff and manage for various purposes.

Studies like this one give credence to the fact that social media platforms such as Twitter, Facebook and blogs will be around for a while.  Their popularity as a very simple and open communication medium with the ability for corporations — or any size business — to more deeply establish relationships with customers over time, as well as their relatively little cost as compared to other forms of media or customer relationship tools (i.e. call centers) is hard to beat.  They can quickly and effectively reach their brand advocates, keep them informed and involved with the brand.
