The only coverage in the entire southeastern US is a gas station in Alabama. It's an interesting project but "openly licensed streetview" is overselling it by several football fields in any country.
It has the potential, but framing sets expectations and mine were not met. This is feedback for the author and anyone around the project trying to come up with a pitch. Focus on what it could be, don't try to say it is something it isn't (yet).
The same cannot be said of one person in one day for mapping the data on OSM.
Expect Panoramax to grow way faster than OSM :)
This is obvious by looking at the coverage the world. France it where the majority of the coverage is. The coverage of most cities is actually pretty impressive for a young project.
While the UI and coverage is not necessarily on par with street view, it's still pretty usable in France.
Secondly Panoramax is first built for OSM contributors/mappers, not for end users. The blog reflects this in the tldr: "If you are interested in contributing"
