Gregory's Server@zverik @bdon @openstreetmap This is not really similar to Linux at all then. Mapping and make data doesn't require the mapper to be a developer. Developers are needed for infrastructure. You also need expertise in design, and people with product vision who can lead and rally a team. It's hard for mappers to be developers, designers, product owners, all in one person.
Many OSMers don't care about usability. Or if somebody actually sees their work. Many like me mostly use Google Maps and Waze.
@cbed @bdon @openstreetmap I'll answer to each tweet :) So, this is indeed unlike Linux, but a bit like Wikipedia. They have got millions of editors, but very few developers — some volunteer, some they had to hire, because people rarely align to tasks.
Another example is HOT. They are primarily mappers and community builders, but they have to hire developers to make their operations effective.
An opposite example is the TomTom OSM team. They struggle with what tools other people made.
