If you’re in the New York area, you may have heard of Schneps Media or at least you’ve seen their publications.
Schneps run dozens of local newspapers and they’re standardized their digital versions on WordPress. Their sites focus on specific areas and communities in New York. They cover local neighborhood news, Spanish-language groups, LGBQT issues, Caribbean community, and now sports. Here’s the full list of papers.
A typical example site in the network is The Queens Courier. To run the network, they appear to have a custom plugin installed to allow them to publish centrally to all those sites via the WordPress REST API.
