Content Management system recommendations

Management is thinking of changing out Content Management Systems. What do you use/recommend?

1. What UCM solution is your company using?
2. How big is your company?
3. Are you happy with the implementation?

Current setup:

1. The company I work for uses Oracle ECM (formerly Stellent UCM).
2. We have somewhere over 10,000 employees across Australia, New Zealand and Indonesia.
3. It works! Having worked with the system for a while now. I can see where the initial implementation went wrong. Its 3 years later and it is Rewrite Time! (Three year itch?)

1) CMS: Oracle's BEA Aqualogic
2) Size: 10,000+
3) Experience: As an end user with full community and content admin privileges, I find the tool to be outdated and stifling in terms of knowledge sharing and trying to get the benefits that exist in social networks. Perhaps this is due to the implementation, and not an inherent weakness in the product. Not sure of the future direction of the product either, since Oracle recently acquired it.
