Hmmm... I guess the main problem that people have is that a tag like "importance" (or its synonyms) is inherently subjective and a subjective tag is hard to determine "on the ground". Given the recent discussions about unofficial cycle routes and the secondary roads in Ipswich, people seem to be just a bit allergic to things that can't be surveyed.<br>
<br>For what it's worth, I viewed the purpose of the importance tag in the context of a general-purpose map which OSM is by default (though it can and does support specialist maps like the Cycle Map). I guess such importance/popularity/prominence data can conceivably be compiled as a separate database to be maintained by those who are interested in it instead of being included into OSM.<br>

</div>well, navigation is not the only purpose of maps, and in this example<br>
the mountainpeak might be a better landmark than the park.<br>

</div>yes, and sometimes there is a very important feature and no road to<br>
it. By using this kind of algorithm all motorway-crossings become<br>
"important" features (which they are to people in cars, but they are<br>
not to pedestrians, archeologists and cyclists).<br>
