Following Facebook’s release of an iPad app last week — an app that has drawn a “too little, too late” response from critics so far — WordStream Inc., a provider of search marketing software and services, released a “Facebook Wall of Shame” infographic detailing Facebook’s criticisms, missteps and outright failures over the seven years since its inception.

The social networking company boasts approximately 800 million active users worldwide and an estimated $4.27 billion in estimated annual revenue — but you don’t approach the 1-billion-users mark without making a few mistakes along the way. Facebook’s errors in judgment have included:

• A slew of privacy snafus: Facebook repeatedly faces criticism for its user-unfriendly privacy policy and default settings that force daily overshares.
• Constant UX changes: Another day, another Facebook update. The latest changes include a real-time ticker sidebar that turns your friends’ updates into a stream of spam.
• Facebook Deals: Facebook’s attempt to compete with social deals companies like Groupon and LivingSocial was short-lived — in fact, this venture lasted just four months!
• Facebook Lite: This was supposed to be a less bandwidth-hungry version of Facebook for use on slower networks, but the company killed it after eight months.
• “Quit Facebook Day”: In June 2011, Facebook lost 6 million US users, the first time that figure has dropped since its inception. The addictive, mood-killing quality of Facebook along with privacy concerns have driven former fans to quit in droves.
