It's another CMS system... of which there are dozens maybe hundreds...
I suppose unless your company adopts it or you develop content for it, it would be a waste of time for you...
It's not really on the radar so to speak... i doubt it'd be in the top 20...
This should give you an idea of how many are out there:
Proprietary Content Management Systems
That is not a complete list and there are still all the Open Source and Hosted CMS Systems....
