I added a friend based on request.  It seemed virtually the same as the Linked In procedure and worked all right.  However, finding the "create a new blog post" took several minutes of guessing and hunting before I found the right screen and tab to create this blog.

 

My initial impression is that this is the same as Linked In, and if I were to belong to one, what I am doing now with the Cisco Community is a duplication of effort.  I ask myself, "If I had not been invited to participate in the beta (and thanks for the invitation), why would I want or need to belong to Cisco Community and Linked In?"

 

Perhaps the answer will reveal itself during this beta along with other secrets of the universe.  More comments to follow...
