I'm guessing I can only add places via the app? I'm currently sitting at my desktop machine, but could easily add at least 5 Cafés with WiFi near Charing Cross in London. However, I don't have an android or iphone, so am unable to contribute. Maybe letting people log in to the web version and let them add places? (and also maybe bulk uploads, i.e. every Costa and Starbucks has WiFi and it's trivial to get the location data for those stores.)
