That's interesting, but it seems like comparing one small area to
another small area may be insufficient in the context of...the entire
world :)

It also discusses a different type of imported data - land use. As a new
mapper myself, it's certainly more difficult/intimidating to deal with
shapes and ways than it is with points. (I'd also guess that an import
of this kind of data is more subject to error, but that really is a
guess). An address import, done correctly - as I understand it! - will
either just merge an additional bit of data into an existing shape
(which doesn't seem to change its 'level of intimidatingness' to a new
user much), or add a simple node with a bit of simply-understandable
data - a street address. I found it much easier to grok something like
this in my First Hour With OSM than it was to grok shapes and complex
things like different types of paths and land use.

To give a single anecdotal personal perspective - I'd be much more
likely to contribute to / continue contributing to OSM if a reasonably
comprehensive set of address data was in some way available for my
location, because probably 80% of my use of maps is 'where is this place
and how do I get there?', and street addresses are obviously highly
useful for that. If I can do that in OSM, then I'm more likely to *use*
OSM, and hence more likely to want to add further data to it - like,
once I find my way to a place, maybe I'll add the building shape and the
business hours and so forth.

If I can't do my main practical use of maps in OSM, then I won't be
getting anything immediately concrete out of contributing to it -
because I'll have to use something else for most of my actual practical
mapping needs - so it becomes somewhat less likely that I'll contribute.

But of course, that's a single insignificant data point. From what I've
seen in OSM-land so far it certainly seems like a lot of people use maps
in much different ways, where address data is insignificant /
