A timely snapshot
Facebook has had its fair share of bugs, partly reflecting frequent changes and additions to the company's website. But some incidents have escalated to major embarrassments, because of their potential to allow peeks at personal information that Facebook's users may not have intended to be widely viewed.
In one incident earlier this year, Facebook misrouted the private messages of a small number of users.
The incidents don't seem to be affecting the site's growth. Last month, Facebook Chief Executive Mark Zuckerberg said the 400 million-person service was adding users at its fastest-ever rate.
But the slip-ups could continue to serve as fodder for critics and regulators investigating how Facebook handles its users' data more broadly.
