Couldn’t agree more, these big companies do not seem to get the whole open-ness angle right. I don’t think their roots will allow them to. I head IT for an advertising company based out of Singapore. We did try Sharepoint and lotus connections for our intranet, extranet kind of collaboration requirements. Sharepoint is a monster that takes months to configure, architect and then you realize you haven’t gotten the information architecture right and start all over again. IBM connections is fairly low on capabilities and large on claims. Finally we gave up the bias of looking at the top 10 software companies’ products and evaluated Confluence, Cyn.in and Alfresco. They ALL were leaps and bounds more usable and adoptable than the big company software. We finally chose cyn.in as it gave us the perfect blend of features and usability. Also the fact that Cyn.in (and Alfresco) were open source, really helped.
