Personally, I have already been finding them useful as a node for meetings. So you can hook the meeting to a hub node, and navigate from there. So with “muscle memory” I can without thinking navigate to the linked information. The last thing I want to do in a meeting is bring up Spotlight or a launcher to get to information I need to consult immediately.
You can also do Copy All Links on the hub to connect everything to the meeting so that it is all within 1 degree, no navigation required.
It may be helpful to have some videos along with a blog post with images.
