Here's a funny story.

Some chaps came over to our London office from the Czech republic, and after I'd spent the day giving them a training course, they asked me some questions about how to get to Big Ben and Tower Bridge etc. Naturally I pulled up an online map on the projector screen, and naturally it was openstreetmap.org . Openstreetmap has been better than google maps in central London for a long time now. They were impressed by the detail. Even their hotel showed up on the map, so they started asking me questions about it.

Part of me was thinking "No. please don't get me started. I'm supposed to be enthusiastic about our company products, not OSM!" So I casually described the project, and tempered their enthusiasm (and mine) by pointing out that London is an extreme case. The coverage isn't that detailed everywhere. For example let's take a look at the city where they are from: Olomouc ...oh wow ...OK

Maybe OSM coverage really is expanding at an increasing rate.
