One-third of Facebook users are spending less time on the site than they were just six months ago, a new survey suggests.

According to findings from a poll conducted among 1,032 Americans by Reuters and research firm Ipsos, 35% of Facebook users said they are less engaged on the social network than they have been in the recent past. Only 20% of members are spending more time on the site.

It lso found that four out of five Facebook members have never been influenced by ads run on the site. This indicates that marketing efforts that encourage Facebook users to buy products and services via the site may not be working.

I now spend less time on Facebook..how about you? Are you no spending less time on Facebook than you did 6 months ago?
