Stealing the headline completely from Matt Lynley of Venture Beat (and one of my former students) to point to the growth and changes in Yammer as it moves toward a comprehensive activity streams service.
Yammer is doing exactly what I’ve been talking about in moving beyond email and integrating services and activities in a more effective way. I haven’t used Yammer in a while, but it looks like time to revisit it.
One downside for me and the #noemail project is that Yammer is designed for intranets. Great for companies, as is Lotus Connections, but I want to try working in public and in the wild.
