If we want more participation, we're going to need to find those people who are interested and even enthusiastic in this subject. That's a very niche audience.
I suggest we/someone make an effort/research to list all people who would be interested in this subject matter and then (subtly) contacting them to let them know about it.
Note: I don't know stackexchange rules about this. In all cases, my suggestion is to be constrained by stackexchange rules and policies (and this question may be edited by anyone to reflect such).
We would need to keep track of sources, contacts, and status. Maybe on a private wiki. A lot like culling leads in a sales team.
- #1: Educators who actively promote the teaching of science and math history.
- Any teacher/professor of a math history or science history class.
- Find out which universities have such classes.
- Journals, articles, books, videos, movies that write on the topic.
- Authors of said media.
- Readers of said journals (perhaps via Amazon, book reviews, etc.)
- Anyone who wrote a thesis or dissertation on the subject.
- Websites on the topic.
I wouldn't suggest being spammy about it. But those are the people who would have a vested interest and enthusiasm in participating and there you will find a core group.
Please comment / add ideas / etc.
