Last weekend I attended an amazing Open GIS http://gisconf.ru/ conference in Moscow. Many good topics, great energy, lots of people wanting to help us build the best maps on the planet. I gave two presentations, one about the overall state of our maps initiative, and one on the tech we have built.
As part of the discussion, the GeoHack for the Russian Wikipedia was updated to use our maps, so we had a six fold increase http://searchdata.wmflabs.org/maps/ in the number of maps users! Will see how it may change during the week. As part of the KPIs, we should add per-country graphs https://phabricator.wikimedia.org/T119448 (top 10 only).
Other results might take time - people learnt of our technology, and I learnt some of the projects we may benefit from, for example I learnt of the simplestyle https://github.com/mapbox/simplestyle-spec/tree/master/1.1.0 and GeoJSON+CSS http://wiki.openstreetmap.org/wiki/Geojson_CSS (will allow our editors to style custom objects they overlay on top of the map).
In short, it was a fun weekend )
