Tired of socialnetworking?Logging off Facebook?You're probably not the only one.Fearing fortheir privacy or perhaps just bored with using the site,100,000 Britons are

said to havedeactivated（注销）theiraccounts last month. And Facebook fatigue seems to be catching. Six millionlogged off for good in the U.S.too,figures

show.Worldwide,therate of growth has slowed for a second month in a row一and as it aims to reach its goal ofone billion active users,Facebook is having to rely on

developing countriesto boost its numbers.The figures suggest that there could be a"naturallimit" for Facebook's saturation（饱和）.There is even speculation on blogs that,

as is feared for itsfailing rival MySpace,the website could one day "pass into oblivion"（被人遗忘）.

2.Earlier thisyear,executives announced that the number of Facebook accounts held in the UK hadreached 30 million,accounting for about half the population.The milestone

was an increase offour million from last July and represented the highest saturation of anycountry in Europe.

3.But times change一and last month more than 100,000 inthe UK stopped using the website, figures show.In the U.S.,user numbers droppedfrom 155.2 million to 149.4

million throughoutMay.In Canada there was also a fall,of about 5 million users,while in Russiaand Norway num-bers also fell by more than 100,000 users.

4.It's not all badnews for the site.Worldwide,Facebook is still expanding and has around 600million users,thanks to strong growth in countries such as Mexico and Brazil.

5.According to EricEldon,of the website Inside Facebook,which obtained the figures throughanalysis of the company's advertising tools,there is a point at which the sitecan

no longer grow, onceit has established itself in a country."By the time Facebook reachesaround 50 percent of the total population in a given country,growth generallyslows

to a halt,"heexplained.Paragraph1_________
