There are indeed many medical editors, but they are not the "most" as you said. I want to give you this impression for the following reasons:
First, the medical industry is expanding to the network, and the number of medical editors is indeed increasing;
Second, the medical industry is profiteering. With fierce competition and deep pockets, they attach great importance to promotion and have more exposure;
Third, the number of websites in the medical industry is generally small, and the division of labor is not very fine. Editors generally serve as promoters, and many promotion methods are manual labor, not mental labor. So they will frequently appear in various forums, groups, Weibo and so on.
It should be the bright spot above, which caused your wrong impression.
There are all kinds of websites in the world. Any large portal website has more editors than N medical websites, but they have a special promotion team with a detailed division of labor, rather than editing directly.
If you are interested, you are invited to join our knowledge team-network editor, waiting for you.
