Google+ got a slew of photo-oriented features at a special event on Tuesday, including much-improved , and new HDR controls in Snapseed. However, the occasion also new insights into the performance of Google's young social network. The company now counts 540 million Google+ users across all of its sites, uploading 1.5 billion photos each week. These are both giant figures for a service that launched slightly over . While the milestones don't directly compare to Facebook's achievements, they hint that Google+ has created a distinct audience thanks in part to its photographic prowess.
Facebook mentioned in this September that its members are uploading 350 million photos a day, or nearly 2.5 billion photos every week. The company is clearly beating Google+ in terms of volume, but it also has more than , a seven-year head start and frequent cross-posts . That Google has reached 60 percent of Facebook's image traffic without those luxuries shows that it's doing something right for shutterbugs, even before today's upgrades.
Some of that group is no doubt relying on Google+ solely as a hosting service -- out of those 540 million users, 300 million use the social stream. Even if only some people are posting directly to Google+, though, that still makes it a valuable place for sharing pictures. And many are genuinely interested in socializing; for proof, you just have to look at the relatively high number of pro photographers who've embraced the service. Well-known pros like and spend a lot of their time on Google+, and some of them have millions of followers. It's reasonable to believe that large numbers of those fans are sticking around.
Mark Zuckerberg and crew don't necessarily have reason to be worried in light of Google's expansion and new photo technologies. Facebook has been as of late, and photography is just one piece of a bigger social networking puzzle that includes games and location-based services. However, the rapid growth of Google+ as a photo platform shows that it's filling a void left by its rival. Vic Gundotra said at Google's event that images are some of "most important things we have," and it's clear the company is banking on that to draw us in.
