- The average Google+ post has less than one +1, less than one reply, and less than one re-share.
- 30% of users who make a public post never make a second one. Even after making five public posts, there is a 15% chance that a user will not post publicly again.
- Among users who make publicly-viewable posts, there is an average of 12 days between each post
- A cohort analysis reveals that, after a member makes a public post, the average number of public posts they make in each subsequent month declines steadily. This trend is not improving in newer cohorts.
The obvious question to ask of that analysis – which, as a caveat, is only made against public posts (because private posts are, well, private, and there’s no way of knowing how many of them there are) – is how it compares against other social networks, partciularly Facebook, Twitter and the new kid on the block, Pinterest.
