I brought the point up because when searching GoogleEarth before and looking up houses of friends and family, I often noticed that some of the time it indentified one of the neighboring houses as the target property and thought it was a little odd. It's looking good though. Keep up the great work! That was a great insight into the world of Geocoding.

However, they don't type in each address - they divvy the block up into even sections and "guess" the address from that. Part of what you're seeing with Google earth is also geo-referencing error on aerial imagery it's hard to get aerial photos of 3-d surfaces accurate to the meter; if you look at the space needle, it looks like it's leaning to the side. This is because the airplane (yes, airplane!) was not directly over it when it took the picture. I'm guessing you're well aware of this, but most folks aren't. So, you're right: no complaining people - those points are pretty close!
