Interesting set up. I can see how it can better control internal correspondence for businesses. Had it come before email it could have been an industry standard. What I don’t understand is why corporate actually accepts email, more loose, more liability, to something like Yammer.

Fyi, they’re going to make a version that can be set behind a corporate firewall to appease the corporate masses.

I don’t like the new trend of Twitter going mainstream. It used to be just colleagues and other techies I found interesting like you say. It seems like it is turning into facebook. I don’t need Twitter to turn into a place where I hear, “I am going for a walk.” Keep that at Facebook. Twitter is a place to hear about what is going on in the industry and tips.

I too keep the segregation between twitter and facebook.
