We have some public telemetry data about "geolocation accuracy” for our nightly users. That tells us that more than 80% of those users get a GeoIP based result today, with the accuracy being well over 20km. Nightly users with activated telemetry are a very small percentage of all users, but I think for this purpose the number should be a good overall indicator.
I thought telemetry was enabled by default in Nightly and Aurora channels (and soon Beta)?
Hanno: are you referring to the telemetry data about geolocation accuracy on telemetry.mozilla.org? What are the "Start" and "End" columns measuring?

I think that most desktop users still have stationary devices, and their home or office WiFi networks aren’t in any database. If we added them to our database, I fear we’d just end up with many unconnected islands of networks, but nothing to connect those. We’d need someone with a GPS capable device to capture at least one of the networks, to anchor it with a good position. But if we have someone stumbling in the neighborhood, than that person will also likely pick up most of the networks our desktop users have seen.
I think you are right if we have someone using MozStumbler to thoroughly scan a neighborhood, but we only have a few hundred active MozStumblers. When we add more aggressive stumbling (but still opt-in) to Fennec, we might have tens of thousands of people submitting many short scans. If we have a large network of dark APs from desktop stumblers, then GPS positions reported by Fennec users might transitively "light up" a larger area. Keven Everets gave an example of someone scanning a street with MozStumbler and transitively providing position data for dark APs on side streets. But I agree that we would still have many disconnected islands of APs.
