I am just an average guy who is fascinated by all crowdsourcing projects on the internet. I try to support as much as time allows - especially on OpenStreetMap and Wikivoyage.

I have written some small web applications that I hope will be useful for some contributors:

• Rio de Janeiro - Rework the See and Do sections. Maybe best is to archive the current text and start from scratch. Link to district listings as described here.
• Rome - Dynamic map of Rome with self-made map in Commons Wikidata items.
• Tokyo - Draw Harajuku, Ōimachi, Gotanda, Asakusa, Ebisu and Ueno. Either directly in OSM or upload GeoJSON to Commons.
