1. Go to maps.google.com
2. Now click the New link, located on the right top of the webpage
3. Once you click, the new link you will see a pop up showing you all the google maps labs beta feature which you can explicitly enable to use, locate the feature short URLs and click to enable it and click Save changes as shown in the image below.
4. Once you have enabled this feature, search and locate the address on google map and then click the link the top right of the google map interface, and you will get the short URL which you can right click and copy and share with any one on twitter, facebook and IM etc.
