Facebook’s cratering stock price is far from the social network’s only problem these days. They are also dealing with a customer base, which is getting increasingly bored with its service.

According to a new poll by Reuters/Ipsos of 1,032 Americans, 34% said they are spending less time on Facebook than they did four months ago.

Another of the poll’s findings that is sure to make Mark Zuckerberg and company uneasy is that only 20% of Facebook users have ever bought a product because of advertising or a comment on the social network site.
