Hugh Pickens writes "Blake Snow writes that evidence suggests that a small but increasing number of users — at least in North America, where Facebook use is especially saturated — may be shunning the site with Facebook losing nearly 6 million users, falling from 155.2 million at the start of May to 149.4 million at the end of the month, the first time the US has lost users in the past year. Some users complain they're spending so much time on Facebook that they're short-changing the rest of their lives. 'I figured out that I wouldn't look back as an old man and wish I had spent more time on Facebook,' says David Cole, an IT manager from Boston, adding that he believes the popular social-networking site is a useful tool, but not a replacement for what he calls 'realbook' experiences. Kip Krieger, a college student from Virginia, says Facebook has become predictable. 'It's really gotten to a point where I know pretty much what my friends are going to post. They usually just write the same thing over and over again, and I am getting sick of that.' Still there are a lot more satisfied customers of Facebook than disgruntled ones, so are Facebook shunners a tiny minority or part of a growing trend? 'Having that connection with others is a very powerful thing,' says Toby Bushman who felt so much pressure that she decided to rejoin Facebook, and is glad she did. 'It makes me feel like I'm a part of something bigger and more grand than just my life as a stay-at-home mother.'"
