Facebook Problems: Evan Priestley, Former Engineer, Exposes Social Network's 'Buggiest' Software

Has Facebook developed the glitchiest software on the web? Yes, according to Evan Priestley, a former Facebook engineer.

"Facebook is the buggiest software I use regularly, by a wide margin," Priestley recently wrote on question-and-answer site Quora. TechCrunch reports the Priestly has also documented more than 30 Facebook bugs he's found since September, collecting and publishing the glitches on a Pinterest blog.

Though Priestley has made it his hobby to reveal the social network's flaws, he actually defends the snafus on Quora, writing that there's no need for the company to make higher quality software. Priestley writes that the company has paid less attention to developing software and, thus, has been able to put more energy into making the company a fun place to work and attracting new employees.

If this is Facebook's plan, it seems to be working. According to Glassdoor's Employees' Choice Awards, Facebook was rated the best tech company to work for in 2011. (Check out our slideshow featuring the highest-rated tech companies of the year.)

Another reason Priestley says it's okay for Facebook to have a few shells in the omelette has to do with the type of company it is. Because Facebook is a social network and not "banking or space shuttles or nuclear reactors," users will put up with the occasional problem. If you can't update your status for a day, or even a week, it isn't the end of the world.

Facebook may take the bugs more seriously than Priestley realizes, however. In July 2011, CNET reported that Facebook had launched a bug bounty program, promising to reward $500 to third-party "whitehat" hackers for each bug they found. In August, Facebook paid out $40,000 in bug-finding fees, reported CBS San Francisco.

A few of the issues that Priestley documents on Pinterest are duplicate notifications, broken links, rogue smart lists, grammar mixups, phantom "Like" symbol on posts that no one has liked, and more.
