So Esri has taken down its vBulletin based Forums and put up a Jive (v7) based collaborative site called GeoNet. Threaded content of the June 2010 - June 2014 epoch forums was migrated over the July 4th weekend.
A bit of square peg - round hole in forcing the well defined vBulletin Forum topics into broader Jive "Spaces", but as Jive is more about tag driven filtering and search it is not that difficult to find specific content.
What is less clear is how much of a knock the Esri hosted forums will take with the migration to Jive's much less focused format. And, I guess conversely how well is GIS Stack Exchange positioned to take up the slack?
The new GeoNet has some nice features compliments of its Jive underpinnings (blog and document content), but are users going to wade through some of its sludge to get answers to their questions, or use it to follow discussions? Are heavy contributors going to stay on?
I don't know--I do have some skin in the game. But the Esri forums have lost their one major advantage over GIS SE--that is a well structured hierarchical and historical archive of technical support exchanges. It has now joined GIS SE as an index and tag driven search engine. Frankly the Stack Exchange based model has that aspect mastered.
I'm just not sure if either is going to be very efficient in walking folks through installation and configuration steps that seem to have become my lot in supporting GIS. Not so sure it is going to be worth the effort, but you're welcome to visit with me on GeoNet ArcGIS for Desktop Installation support group if you like.
