In case Facebook’s perpetually sinking post-IPO stock price and a handful of pesky class action lawsuits isn’t causing enough of a headache for the social networking giant, a recent study found that more than one-third of Facebook users find the service useless and boring. A recent poll of Facebook users conducted by Reuters found that 34% of respondents use Facebook less today than they did six months ago. Among the reasons given for the drop in usage: Facebook is “boring,” “not useful,” or “not relevant.” 20% of respondents claimed to use Facebook more now than they did six months ago, and 80% say they have never purchased a product or service as a result of an advertisement or comment seen on Facebook. The results of a separate study released last month found that nearly half of Facebook users said they would never click on an ad while only 3% claimed to regularly click on Facebook advertisements.
