This post should have been posted a long time ago...
Being part of a big company was great. One of the great things it brought me was being a member of the 2.0 Adoption Council. The 2.0 Adoption Council is a group of Enterprise 2.0 practitioners working for large companies. I was a member of the Council for a couple of years. It was a great source of inspiration for my work. Lots of smart people are in the Council.
Actually I was humbled to be part of a group of enterprise 2.0 practitioners that are seen as the leaders in this space. Some had many more years experience than I did. You wonder what they get from the Council? Well, that's one of the great things about these communities: we're all in it to learn and help each other. And that's exactly what happened. Even though some have been in this space for a long time, we're all still just getting started.
To cultivate interaction we used Jive, Yammer and Socialcast. And email of course. Even more important were the meetups around conferences. It was great to meet many of the Council at the Enterprise 2.0 Summit in Frankfurt.
One special thing I'll remember is the Council giving me the opportunity to experiment with a prediction market. I don't see many companies using them yet, but I'm sure they will be in the (near) future.
So, if you're working for a large(r) company and experimenting or responsible for enterprise 2.0 roll-outs, I wholehartedly advise you to join the Council. Information about joining can be found on the Council's website.
