This sounds like an interesting project.
If you go to the site, you can search for a church via your zip code … and it gives you a Google Map to some area churches. Pretty neat!
The site basicly returns a Google search with your zip code as the variable — pretty simple but effective combination.
I guess it would work for people looking for a church to join as well. Good example of the web helping connect real people in real community…in this case, with a bonus spiritual dimension for those who are seeking that.
