Slightly surprised to find the Adulting, Career Guidance, and Jobs communities haven't gained too much traction, or in one case stalled out. Although these communities aren't the most exciting or uplifting, so it also makes sense.
I'm talking about the following on Lemmy World specifically:
Given the second community never went anywhere, it's probably best to instead focus on Jobs if anyone was interested. Unfortunately in the case of both the Jobs and Adulting community, the moderators no longer seem to be active to coordinate with to help the communities along.
In looking about the only similar communities I could find to these were on other instances one might also consider too large or controversial, if not both (e.g. Lemmy ml and Lemmygrad). Given their lack of activity, if there was enough interest they might be rebuilt on other instances with more effort to get them going. However, seeing as that already seems to be something of an uphill struggle, revitalizing what's here might be preferable.
Thoughts?
Keep in mind that instances (not just communities, but instances) come and go. Worst case, if an instance dies, yes, a community can move to a new instance, but you might want to consider several factors when choosing an instance to start a new community.
If you decide to just take over one of the existing communities whose current admins are no longer active, you can request for the LW admins to appoint you as moderator of said communities. Do try reaching out to the existing admins first. But yeah, if nothing else, you could then facilitate a transition to the new instance, e.g., poll the active users to see if they want to move, and if so, then lock the community and post a link so new users can find the other instance.
