For both current and data at specific points of time
http://overpass-turbo.eu/ is likely to be the best solution. It allows
to get data for specific area without processing massive planet
snapshots.

"provides access to existing users" - I am not sure what you want. Who
was last to edit given element? List of all user accounts? List of users
active in a given region? Something else?

Also - counting all nodes will give poor result. Place with massive
amount of outdated data with dead community that used to be active will
score highly. Place with new, highly active community will score
poorly. At least, one should count only new/recently modified
ways/nodes/elements.
