The My Maps feature of Google Maps has been around for quite sometime, but if you are a regular Google Map user and you're not using it to share common directions, it's worth it.
The Google LatLong blog (Google's official blog for all things Google Earth and Maps) has a simple beginner's tutorial for using the My Maps feature to customize and save directions—complete with notes—so you've got a repository of common directions with helpful annotation.
As I said, this isn't a new feature by any means, but it's something that I've used several times here at Lifehacker (see the embedded map) and to share directions with friends and family. If you've used My Maps, let's hear what you're using it for in the comments.
