i think we'd have no way of knowing whether somebody had included all possible shops in his/her area..
and how wide a radius is "area"?
what counts as a shop?
what doesn't?
the list of variables can get quite long.
it won't be merely better than nothing.
it will be "i can't believe one of our members has offered so generously to spend uncounted hours of time and effort to compile this great list that i might not find anywhere else on the internet."
this glass is definitely full.
