If you haven’t heard of "mash-ups" before they are when someone takes an existing product and combines it with something new and cool. Kinda like a re-mix. Here is a great Mash-Up based on Google Maps, which I have covered before for FIspace. This Web Site let’s you find Wireless Internet spots using a Google Map. No more asking people "Do you have Wireless Internet here?" and having them look at you like your a Nerd from outerspace. Now if you want to know where to find "Wireless Hotspots" all you have to do is type in your location. Check out the sample map below.
