After looking (Googling) on the web for a while, I can find nothing that takes an address like:
1200 Pennsylvania Ave SE, Washington, District of Columbia, 20003
and converts it into a clickable link:
jQuery or PHP preferred or just any useful information on this.
On http://www.labnol.org/internet/tools/short-urls-for-google-maps/6604/ they show a short URL that works pretty well
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.
I used it for a few applications I've designed and it worked like a charm.
