My Top 5 Yammer Value Adds

1) Bridges to so many people all within the corporate world in which I work. People who I would never meet, talk to or get to know without the tool.

2) Realtime discussions and debates on issues being faced today, segmented by subjects that I care about.

3) Answers to any question I can think of from a global perspective (if you work in a global company)

4) Access to a large library of already created work - Don't reinvent just improve

5) Opportunities to meet my goals and to help others meet theirs
