I recently went to Lotusphere 2011. IBM is making a major focus in the social business space, also known as enterprise 2.0. Below is complete listing of my notes posted on Lotusphere 2011. I was very pleased to be back after ten years. I first came to co-present a Lotus Notes based KM project with my client. Now I returned as a blogger. I recommend considering Lotusphere 2012. I learned a lot and had some fun at the same time.
