Yammer was twitter for work. Facebook rolled out its own version before anyone else does. But thats pretty much it. The very fact of facebook having an addiction component will work against it.

I think managers would think twice before introducing a collaborating software where team would end up spending more time than actual work. I think for this very reason softwares like work wikis, sharepoint are so successful.

Also from user point of view, I do not see myself using the same tool at work and then at home. Hopefully they have a radically different UI rather than just changing the logo with companies logo.

We use Yammer at our company and it's much more like Facebook than Twitter. It's not the be-all and end-all of our collaboration tech nor do I think people spend more time on it than actual work.

Yammer _is_ Facebook for work, which is why I'm surprised that FB is releasing this product now, and that they expect much of a marketshare.
