To be brutally honest, there’s nothing we miss and a year in, we still high-five each other every time we speak of the transition.
Reporting has recently been revamped, (nod to @hawk, formerly of Feverbee and now at Discourse), is insightful, but most importantly, is not limited to a dashboard of preconceived metrics. With a data explorer plug-in and a little SQL knowledge, reporting can be whatever you want it to be. My biggest problem is knowing what I want it to be! (I’m eager to see what comes of @richard_millington’s request for feedback on an analytics course, which I see you’ve replied to.
We do not have integration with Marketo or Salesforce, but do have integrations with Slack, Wordpress and Inbenta, and are considering possible integrations with Zendesk. If the integrations you need do not already exist (I’ve never looked into those) figure out exactly what you need them to do and ask Discourse what it would take to build them. I’ve been impressed (ok, to be honest, I’ll have to use the word floored) by the team’s responsiveness to any sort of feature request or integration need. They think through the request very carefully (security concerns, alternate solutions, cost to develop, broader applications) and will, when it’s the best solution, contract with you to build what you need, all very quickly.
On the same topic of being floored by the Discourse team’s responsiveness, bug reports and smaller feature requests receive replies within moments (at all hours) and it is not unusual for them to be resolved the same business day, or even within the hour. I don’t want to turn this into a Jive-bashing reply, but there were serious bugs we reported to Jive that never did get addressed.
We do use single sign on, and have had no issues there.
People posting in the wrong area - in DIscourse your top users earn light moderation rights, one of which is moving topics to the correct area. Discourse also allows admins to not only split topics (“branching” in Jive’s lingo) but also to merge topics, which helps you keep conversations focused in a single place.
I’m not sure if this would solve your need for shared documents, but Discourse does allow the option to wikify the top post in a topic, and it has a “Shared draft” option that allows collaboration prior to publication. Every topic also has the option for staff to “whisper,” or post a reply that is visible only to other staff.
You might consider asking the same question in Discourse’s Community. Since nearly everyone participating there is already on Discourse, it seems your odds of finding others who have moved from Jive to Discourse might be better there. There’s one such conversation already, but it’s quite dated.
Please let me know if there’s more you’d like to discuss.
