I work as a software for the MBTA but don't speak for the organization.

There are pages on the main site about this project, for example: https://www.mbta.com/projects/better-bus-project

I think the Medium blog was set up for posts intended for a more tech-savvy audience than the broader audience that visits MBTA.com to check schedules, plan trips, view alerts, etc. Maybe at some point it will be merged in.

The website was relaunched ~year ago as an Elixir / Phoenix application and there are still quite a few features and content being added.

Perhaps it could be cross-posted?
