I don’t want to discourage you too much, but please observe that you have added *a lot* of new objects to OSM today, many of which were badly-tagged, non-existing or misplaced.

People will not want to use OSM if information they find here is incorrect or misleading.  We have had enough cases of people trying to play games on us by adding fantasy information just to see if we notice.  Doing this might get you banned from editing the map.

information=guidepost is a tag for a very specific type of device.

There is no such object here, as this recent picture confirms.

Let’s assume good faith.  You wanted to map the street sign itself, didn’t you?
