While I wait until next week to share geonews in batch mode, James made me aware of a great MapBox project: the Maki open source point of interest icon set for cartography.
What it is? "Designed pixel-by-pixel to look great at small sizes but scale up elegantly. We designed Maki specifically for TileMill with the goal of creating an international, comprehensive, and stylistically unified point of interest icon set. Each symbol is drawn three times at different sizes to maximize crispness and readability. Maki symbols are based on international recognized symbols, following precedents set by AIGA and other international symbol systems, but preserving a unique look at feel.
Use Maki for everything from adding context to the base map of your mobile app to highlighting critical data on your disaster map. Just download the icons and start using them with TileMill or put them on your server to integrate with another mapping API."
As pointed out by James, The Noun Project jumped in the Maki train. Looking for previous related entries, I found, those two: Impacts of Symbology Changes for Organizations and Map Symbols and A Summary of Thematic Mapping Techniques.
