Why Yammer Failed at My Organization

Summary: An important executive didn't like Yammer. The company had to stop using it even though it had taken off.

I used Yammer at our last startup and at our current startup. While I think there are some concerns with what you potentially may say or don't say on a Yammer feed, the benefits for us far outweigh the disbenefits.

Not to mention most of the stuff people post are pretty vague and would only make sense for those involved. It's a good and valuable tool if the culture and habits are developed correctly in adopting Yammer early on in any company.
