I traded some email with the Maps team and I saw something in a link they
sent me that I wasn't familiar with. To best explain this, first load this
map from Berkeley to Google in a separate browser window. Note in the "End Address"
section, the Google. Now load this map
of Sydney and note the label inside the callout.
If you look
at the urls, you'll see a (text) argument appended to the url. This is a lightweight way of
linking to Google maps without touching on the maps API. As you can see, you can
arbitrary labels to your links like this chocolate shop or this restaurant.
Have fun!
