Facebook’s (FB) newly acquired Instagram is growing like crazy. According the latest comScore research, Instagram pulled in 7.3 million active users per day on mobile compared to Twitter’s 6.9 million during the month of August. Not only that, but comScore found that Instagram users were actually engaging with photos longer than they were doing so with tweets. The research shows that the average Instagram user spent about 257 minutes browsing and using the service versus the 170 minutes spent on Twitter last month.
Even though Twitter still has roughly 7 million more unique visitors per month than Instagram, it’s worth mentioning that the photo-sharing service is only an app and is not available as a mobile website, and it’s only available on two platforms: Android and iOS. Windows Phone 8 is rumored to be getting Instagram later this year. On the other hand, Twitter is available in some shape or form on every smartphone in the world.
One of the advantages Instagram has over Twitter right now is that it doesn’t have ads plastered all over it, which could be a reason why it has such appeal. Facebook CEO Mark Zuckerberg has vowed that he won’t integrate Instagram directly into Facebook and close off sharing to rival social networks Twitter and Tumblr.
