One way to raise awareness of how very much Some Situations Are Different From Yours (SSADFY) is to discuss everyone's concerns as a normal part of teaching, service, research, job hunting, etc. instead of fragmenting into very targeted interest groups by job title. If nothing else, it's a great reminder to the chairs/deans/others who are reading about the breadth of experiences that constitute academia and perhaps encounter suggestions on how to improve working conditions.
SPADFM so part of the point in starting with only a handful of boards when we have only a few handfuls of threads was so people could browse quickly through everything. I'm having deja vu here because that's how I interacted with the CHE fora back when they were starting out. The quick browse through each board is pretty easy since most boards have single digits of threads.
Going forward, what I read in various places is more people navigate the way I have for years using "show unread posts", "show new replies", and "view recent posts" so that grouping by boards is less necessary for those who are registered members. A click brings up the one page of new stuff since I last visited and that's pretty easy to scan.
I will mention for perspective that the CHE Nontenure Track board has had about 30 threads in the past year. In contrast, the CHE In the Classroom board has had about 30 threads in the past month while CHE Job-Seeking Experiences has had about 30 threads in the past 2 months.
If someone would like to curate a thread labeled something like "Useful threads for novices", then I encourage folks to do so. However, all novices have access to this thread and can click for themselves if looking through under 10 boards of averaging under 10 threads each looking for interesting topics is not their cup of tea.
