Posterous Spaces: New User Growth Nearly Triples

Posterous Growth Rate Rises After Launching Privacy Focused 'Spaces'Blogging platform Posterous introduced Posterous Spaces in September, “an updated take on blogging” and social networking that “emphasizes privacy and controlled sharing.” The change was prompted by the rapid growth of private blogs on Posterous’ network (far outpacing the growth of public blogs on the site).

The results of this shift in focus towards private social sharing?

  • Posterous has 3.9 million members
  • user growth is “accelerating every day” and is now “more than double, almost triple” according to Posterous founder and CEO Sachin Agarwal
  • private group sharing is surging 3X faster than public group sharing (via Posterous)
  • users are sharing 4X as many photos and 5X as many videos privately as they are publicly (via The Next Web)

Agarwal admits “We’re making a big bet on controlled sharing,” and believes that “we can help people share 10 times more online once we give them the controls to do this well,” as reported by SF Gate.

Posterous also commissioned a study about the level of privacy social networking users are seeking, particularly regarding photo sharing.  Read our blog post with the results: 61% of Social Networking Users Would Share More If They Had More Control.
