Business.Facebook.Facebook。Work in progress.The stockmarket has lost no time in unfriending the social network.IT IS still gaining members-there were 955m by the end of June-but Facebook has been losing friends ever since it became a public company on May 18th.Delays in trading on the frenzied opening day were scarcely the social-networking company's fault.But not since that first day has the share price closed above its bloated debut mark of $38; and recently it has lurched lower.It dropped by 8% after hours on July 25th when Zynga, a games company that uses Facebook as a base, reported poor quarterly results, and by another 10% after Facebook's own figures came out the next day.It has fallen further since. On August 1st Facebook's shares closed at $20.88, the lowest yet (see chart).New shareholders are not the only ones feeling fed up.On July 30th Limited Run, a New York platform for the online shops of record labels, artists and designers, said it would delete its Facebook page.It estimated that 80% of clicks came from "bots"-computers rather than people, but triggering payments to Facebook all the same.Limited Run added that after it changed its name (from Limited Pressing) Facebook asked it to spend $2,000 a month on advertising to change the name of its page on the network to match.
