Social games have been instrumental in driving revenue to Facebook and extending the length of its user’s visits.  Zynga, the most prominent social game creator, has even negotiated a special, five-year strategic partnership with Facebook.  At first glance it seems that social games can only provide benefits to the $50 billlion company, but a deeper look reveals a problem that diminishes the integrity of the social network.

The root of the problem is well documented: Facebook has intimacy problems.  Paul Adams, a long-time Google UX engineer, clearly defined the problems in a 224 page slideshow 6 months ago.  Soon after, Facebook tried fixing their problems with an update to the Groups functionality, but it doesn’t seem to have worked.  Facebook followed up by stealing Paul Adams from Google, and presumably another revision of Groups is in the works.  The problem is also detailed by Dave McClure, founder of 500 Startups, in his Open Letter to the Next Big Social Network.

This problem has been around since before social games, but the games have made it a significantly harder problem for Facebook to fix.  As a way to encourage users to invite their real friends to play games, game makers like Zynga have added features that make their games more fun with more friends playing.  While this probably works well for a good amount of users, it has also had the unexpected side effect of forging relationships between people that do not know each other.  The prominence of the issue is made exceptionally clear on these games’ walls, which are littered with open requests to “Add Me” as a “friend” on the social network.

This momentum towards adding fake friends is certainly not good for Facebook, and is reminiscent of one of MySpace’s core problems.  At this point, any attempt to reverse the trend will result in a group for “People I Don’t Know” within the profile of many users.  Moreover, it is unclear if Facebook has a desire to preserve the integrity of friendships in the first place.  With social games driving a significant amount of revenue and already being deeply integrated into Facebook’s long-term roadmap, it is reasonable that the social network will remain content with their current standing.

One option is to put pressure on social game makers to eliminate the features that cause these problems, which wouldn’t be completely out of Zuckerberg’s character.  Years ago, he removed applications from main profile pages, which destroyed the revenue stream of many app creators.  One of those app creators, Slide, shared Peter Thiel’s Founder’s Fund as an investor.  I consider this one of the greatest moves Facebook has ever made, but I’m far from convinced they would give the same treatment to social games.  Unlike the early profile page applications, Facebook is profiting off of these games.  Asking the game makers to remove features that help the games go viral doesn’t seem to benefit anyone financially.

Did social games kill Facebook’s social graph?  I don’t know for sure, but the graph is definitely struggling, and Facebook is definitely struggling to find a solution.  Facebook has a place in the future, but it’s possible this hole has created room for a new, more intimate social network to swoop in without Facebook stepping on their toes.  What do you think?
