One of the things that I love about putting all my folk tale translations into a wiki is that I am also using this as an opportunity to remove another #Google service from my life.
My old interactive map was done with Google MyMaps:

My new interactive map (still a work in progress) is created dynamically by a combination of #MediaWiki with the #SemanticMediaWiki and Maps extensions, and displayed via the #Leaflet API (which uses #OpenStreetMaps ).

This gives me _far_ more flexibility in how to construct my interactive map - and it will give me the opportunity to dynamically create thematic maps, too!
