Hi,
In my previous posts on IBM Connections vs SharePoint which you can find here SharePoint 2013 vs IBM Connections 4.5 Social Capabilities - Comparison from the field and here SharePoint 2013 vs IBM Connections 4.5 - Metadata, Office Integration + Mobile support - Comparison from the field, I tried to shed some light on the pros & cons of each platform regarding Social Business & Document Management.
If you read those posts, you might think that I privilege SharePoint over IBM Connections, certainly as a SharePoint MVP. However, it was not the intention, I really tried to make an objective comparison but that kind of exercise is never easy.
The purpose of those posts was to bring some clarity on both products out of a real world experience. I often read here and there *marketing* messages looking like a boxing match between IBM & Microsoft. I must say that IBM is often the first one to bite., maybe because they are in the skin of the challenger in this matter..:? SharePoint is a well known heavy weight for years now...
