Google Maps URLs are pretty unwieldy especially when sending over an IM, tweet or email. MapOf.it provides you a quick way to link to Google Maps by simply specifying the address of the location as a search parameter.
http://mapof.it/<address>
So, for instance, the Google Maps link for the Taj Mahal is mapof.it/taj+mahal.
If you need directions between two locations, then specify the two addresses separated by a slash. So, to get from the Taj Mahal to Gateway of India, the Google Maps link is mapof.it/taj+mahal/gateway+of+india
http://mapof.it/<from>/<to>
While MapOf.it uses Google Maps as the default mapping option, you can also opt to use other mapping options – Multimap (mm), Yahoo Maps (y), Open Street Map (osm), Tiny Geocoder (t), by adding the map service code before the address.
http://mapof.it/<code>/<address>

Note that unlike other short URL services, MapOf.it URLs give you some idea about the shortened URL. [via]
