Sol Wuensch's "Were the previous forums better than this GeoNet Community?" poll, with 14421 views at last count, is perhaps the most commented entry on GeoNet.
Obviously changes must be made, and here I propose a couple of simple changes that may help the average user.
First, let's change the poorly named but trying hard to be hip "Places" to "Groups".
I don't call my Husqvarna chainsaw "Slayer of Trees", I call it my chainsaw.
Second, and here I take a leaf out of the Apple Support Communities book, let's make it easier to find the groups that interest us.
Let's have a peek at the discussions.apple.com website:

This chunk of the website clearly shows a few hardware-oriented forums and one software forum. The iPad forum is neatly divided into two sub-forums, upon clicking the iPad image.
A similar simple and effective breakdown (sans images - I am not a graphic artist) could be something like this:
3D mapping GIS Developers Software
- python - ArcGIS Pro
MOOCs - Arcobjects SDK - ArcMap
- spatial analysis
Web Developers Web GIS
Industry & Government - ArcGIS API for javascript - ArcGIS online
- utilities & communications - ArcGIS REST API - story maps
- forestry
- ArcGIS for local government Servers Older software
- ArcGIS for Server - ArcView
GPS - Geoevent - ArcIMS
- Collector for ArcGIS
Note: This is not an exhaustive list, just food for thought.
