Indicators of the popularity of various mapping systems

More than six months ago, I have already done similar statistics on the basis of data on browsing the pages of the Multi Cards service and now it has again become interesting - has anything changed? It would seem not a very long time, but the changes are very tangible and interesting. In a nutshell:

1. Yandex Maps overtaken by Google Maps.
2. OpenStreetMap catch up with Yandex Maps and by some samples confidently bypass Google Maps.
3. But Bing Maps, though occupying a significant market share, but in general remained at the same level.

Statistics are given for the last month (11.11.2011-11.12.2011), it was collected using Google Analytics, sampling for various indicators was done manually. The main part of visitors from Russia and Ukraine. A bit of foreign traffic. Selected major cities.

Compared services: Google Maps, Yandex Maps, Bing Maps, Yahoo Maps, OpenStreetMap, Kosmosnimki, Wikimapia, ProGorod, Visicom.

Next, some boring diagrams:
