The Pew Research Center's recent study on social networking sites provides Web marketers with valuable information on social networking services and should act as a real eye opener on the social impact of widespread social networking use.

A few key findings of note for Web professionals include:

- 59% of internet users in the survey say they use at least one of SNS.
- Over half of all adult SNS users are now over the age of 35. Some 56% of SNS users now are female.
- 52% of Facebook users and 33% of Twitter users engage with the platform daily; only 6% of LinkedIn users do the same.

Some insightful data for sure. Perhaps most interesting however (at least to us) was how Facebook is being used. According to the Pew Internet sample, on an average day 15% of Facebook users update their own status, 22% comment on another’s post or status, 20% comment on another user’s photos, 26% “Like” another user’s content, and 10% send another user a private message.
