Exactly how does a location make it easier to answer a query?
IMO...unless you have lived within a few miles of a location you are not going to know ground conditions...you may be familiar with local businesses but in that respect NOBODY should put that close of a location on the public interweb...it serves NO purpose (that's what PMs are for)...
If you want to do somebody's homework for them and need to know a region to search CL for them just ask via PM...
Telling a noob that not putting their locale in their info will get them less than the best advice is pure baloney...and for the most part they are just being nosy
