A traditional paper mapper makes visibility decisions, which automated
agents have more trouble with.
For example:  imagine three ridges, all named, all about the same length.
Which should show at low zoom?
A cartographer might know that the local residents refer to the third ridge
most often, and that it is somehow more important.

An automated agent could try: but the data is likely outside of OSM.
 Should it google for the name and count the hits?
Send an email to nearby mappers?

Some manual tweaking of the "importance" has wide applicability in OSM,
despite the obvious disagreements on the exact rankings/
