This is a list of things I would like to see on coinmap.org
1- I don't like the idea to have to be redirected to openstreetmap.org to add/edit a place on coinmap.org. I think should have a top banner with a button like: (add a new place).
I know a website that does something like this, see: http://ae.osmsurround.org/ae/index#
As you can see, the site have a button called oauth/login, so I ask: Do you think is possible coinmap store your openstreetmap login/password? So users of coinmap shouldn't have the necessary to create an osm account or have to login.
When users try to add a new place on coinmap will appear a new window where will be showed a map (Bing satellite layer) where the user will add the placemark. When the user add the placemark, will popup some suggestions of places that are near of placemark, to know if the place is already added on openstreetmap. If the place is already on openstreetmap, the user will click on it, and choose edit it, adding other informations, example: mark that the place accept bitcoin.
If the place is not yet on openstreetmap, will appear the fields to be filled, like name, address, website, phone......
Today I saw a very interesting site that use leaflet and is able to move the placemark with touchscreen hardware. When user (add/edit places on map), I think you should do the same thing, (allow move placemark with touchscreen). See the site: http://map.project-osrm.org/

Do you like the idea? Is it possible implement it? I'll wait to see if you implement it, so I can suggest new things.
