This is really old I know, but you never knows who will need this.
This week I was asked to update a site that hasn't changed in about 5 years. They wanted a map on there. I did try and use the Mobile me widget in the app but this no longer works, stopped working around the time Mobile Me was discontinued.
You can still easily add one go to maps.google.com, type in the address you want and hit return to perform the search. Next, click on the icon with the chain link and copy the code under Paste HTML into a HTML widget on the site.
This way you can still have the map available.
I am always interested in feedback so please feel free to add any comments, or you can mail me here. If you would like to submit a quick tip with full credit and links back to your site then also feel free to contact me.
