But don't you realise that's an enormous improvement? People can have
that argument all day, and the author of the tool can switch it back and
forth three times before breakfast, but it doesn't affect _consumers_ of
the data, because they have a consistent tagging scheme for their
computers to read.

However, if the way something is tagged is the thing under dispute, and
there are two ways you know about and three you don't, any map you try
and create is going to suck.

If we had one agreed way to tag each thing, and lots of arguments about
how to represent that in editors, it would be a gargantuan step forward
in the usability of OSM data.

The problem with a command economy is not that there's a single way of
doing things, is that it's imposed without consultation. Agreeing on one
way of doing things is not intrinsically bad. Road signs in the UK are
all laid out the same way. There is no (or very, very little) freedom
for creative expression on the part of the person making the sign. This
is _good_ for drivers.
