I hope everybody noticed that I put the picture I posted in post 6 up for voting here. It received 17 votes in favour of smoothness=bad and 2 votes for smoothness=very_bad. Can we conclude that because of the very clear majority for bad, most mappers interpret “usable” as “passable/doable” and not as “comfortably usable”?
If so, we need to go through all the pictures in the Gallery and update them where necessary.
