First of all thanks for taking time to check it. On Google Map, yes you type "restaurants in San Francisco" and it will give you all the restaurants on the area. On my web app, you only need to type the location "San Francisco" and it will give you all the nearest restaurants on the area once you click the radiobutton for restaurants under "Show Nearest" options. Ok now here's the difference, say you want to search in another location like in "Manila,Philippines", in Google Maps (assuming you don't wanna drag or scroll the map to find "Manila, Philippines") so you need to retype again "Restaurants In Manila" but on my web app the moment you start typing it will retrieve immediately all the nearest restaurants on the suggested location until you finish typing the whole world "Manila". Then if you change your mind again and want to check out nearest restaurants in "London" it will retrieve all the nearest restaurants on the suggested location until you reach London. Hence you don't need to retype again and again "Restaurants in #somewhere#".Anyway, the single purpose of my app is to find the nearest interesting point for the user assuming he/she knows the location but in Google Maps I think it's more of a general purpose since you can use it in whatever way you want like for browsing the world, driving directions etc.
Are you overthinking it - if I'm looking at restaurants in San Francisco, chances of me wanting to look at them in London or Philippines at the same time? I'm also a fast typer, so don't see it as a major burden myself... I'll have another play later
