Take a look at the current text of the help center page, What topics can I ask about here?. There are a few different issues with this page as it stands:
List of related sites
The list of sites where questions might fit better could use re-thinking. Historically, five questions have been migrated to Gardening. No other site has had more than one question migrated. These are the other destinations (one question each):
- Home Improvement
- The Great Outdoors
- Earth Science
- Electrical Engineering
- Motor Vehicles
Neither Personal Finance nor Physics have ever been a destination, despite being on the help page. I believe we should adjust the list, and expand the description a bit for each to address the possible overlap.
For instance, I have seen a fair number of questions about specific solar PV setups that might have done better over on Electrical Engineering SE.
Area 51 recommendation
At the bottom of the page there is this text:
If no site currently exists that will accept your question, you may commit to or propose a new site at Area 51, the place where new Stack Exchange communities are democratically created.
However, given the latest guidance from SE staff, an Area 51 proposal should only be submitted by an existing community in need of a Q&A site. I think we should consider removing this line from our help page.
