I had dinner with a friend a few months ago. He is the head of a 500-person company, and he was telling me how he wished there was an off-the-shelf mobile app they can use as an internal directory for his company, given the company was at a size where not everyone knew everyone. So that he could walk into a meeting and his phone would tell him who everyone is, what they do and how he can reach them later.
I told him Yammer was probably that product. He had never heard of Yammer. A few weeks later I followed up to see whether he had installed Yammer and he said no, he was too busy to get around to it.
The Financial Times is now reporting that Facebook is testing a Facebook at Work product. Or, basically, another Yammer; a closed social network for companies. The reason why I think it can work is the reason my friend hasn’t heard of Yammer — everyone knows Facebook and is already on it.
