I'm adding OSMF-talk since it concerns what I outlined in the original “vision
statement” email.
I was perhaps too specific and jumped ahead saying “world’s best addressable
map”.
What I really mean is the “world's most complete open map”. There are three
pieces to a modern map. There's the display piece, the routing and the
geocoding.
We won the display piece. It looks great. We are ok at routing. Not perfect or
great, but ok. We're really lacking on the addressing. If we can get addressing
even to the “ok” stage then a lot more people will use OSM, which means more
editors, more community and more data. This is because the main use for maps
today by the public is to get somewhere, and we can't help with that without
all three pieces. Right now we have 2/3.
I jumped ahead because I see this every day, and I understand not everybody
does. I think all the other things are good too, even every tree in OSM! I just
know that if we had to pick one thing to focus on it would be addressing, as it
will get all the other things to happen faster too. But that doesn't mean you
can't add trees in to OSM at the same time, just that the shortest path to
getting more of everything is to get more of addressing.
Also let's be clear - addressing isn't easy. It's complicated and hard. But
that's a good goal to have, and OSM was complicated and hard in the first place.

I agree that addresses is a complicated field. There are different historical
systems, there are cities where even many streets are without names, etc. There
is a lot of space for innovation, certainly.
What I meant is that it is not obligatory to map a city or a town addressable
from one end to another, one house after another, or wait until a municipal
government releases into public domain its database of addresses (which may be
not without errors or omissions too).
If there are, say, 10% of buildings where 90% of the population lives, studies
and works, it makes sense to map them addressable first. Often these are large
modern buildings with clear addresses.
And it is much easier to return into the same area for the second time, when
there are already at least some large buildings with numbers, much easier to
orientate oneself.
I see from your example that in the city of Reykjavik almost every building has
a number, so you have a more advanced set of priorities.
Best regards,
Oleksiy

I like addresses but they don't behave like you would think. For example we
have a part of a street that has each individual flat as its own address
number. We first used the number;number;number; approach but I'm now in favor
of naming the house what it says on the front (the range 37-51) and then put
address nodes on the building so it appears in search, with roughly the
position accounting for where in the house the apartment is. In this case the
numbers closest to the street are at the bottom floor (the stadium approach I
favor). I'm in favor of moving this same method over to the other houses.

As for being able to search within a specific town or area then I think we
should look again at relations and super-relations. You could group streets
relations into a neighborhood relation and then into a town or municipality
relation etc. This of course works very differently based on country but for
Iceland I can't see us hitting any limits.

It is not necessary to put down a number on each building. It is possible to
use addr:interpolation (odd, even, or all).
We put down a number on the first building, then on the last, connect them in
JOSM, and add addr:interpolation: all . For example here:
http://osm.org/go/0CFn0AZ_d--?m= . It is also very useful on a street with many
small houses. And it is searchable. For example if there is number 15 and
number 27 on the map for a street, and they are connected with
addr:interpolation: odd, and if one searches number 21, the map will show the
number 21 all right.
Then, there is another approach. We first map addressable large building, where
a lot of people live or work. Kind of of going after the low-hanging fruit.
