Ever needed to lookup an address but didn’t know how? Maybe you knew exactly where a particular location was (like on a map), but there wasn’t any way to find out the house number except by driving by or making phone calls. Well, if you’ve ever found yourself in this position, check out this mashup of Google Maps.

I don’t know the name of the service as it isn’t really posted. Just go to the link and start using. The creator of this mashup links to a tech blog (not sure if it is theirs or not) with all kinds of other useful tech tricks and tips as well.
