Jive is an "enterprise - WorkFlow Collaboration" solution > https://www.jivesoftware.com/products/jive-n/ - the "discussions" is only a minor component of the Big Picture. Many outfits seems to use it for its "enterprise level" (Bazillions of users) abilities alone - but I'll betcha some of the "Customers" on the TAB on the above linked page have some good things to say.
To be fair, AppleJiveWare seems to have all the components intact - they are just reserved for Status Level bonuses - the User Tip creation is the "document collaboration" component of Jive-n.
BTW, the "content cannot be saved..." error is a result of JavaScript not being very forgiving (or rather getting all 'alert-ie' about handling the errors) - if one persists, it usually keesps on slugging...
The JiveMobile App is the answer for RealJiveWare - I think it likely that it would cause more problems here than it solves.
I have said it before, the AppleJiveWare UX design is a hybrid meant to be usable but not designed to excel on either platform. Solved by Hiroto writing CSSes for mobile view like he did for desktop?
ASC is a buffer for RealApplePeopleSupport - saves $$ = therefore benefits the shareholders. (Imagine 'volunteering' to go to Africa and work in the ebola camps with crumby tools and safety measures - kind of the same here?)
JiveCommunities takes care of their forums - regular maintenance and periodic re-indexing of the databases. Seems to work fine > https://community.jivesoftware.com/ = join up and take a look around, you may find some familiar folks there.
