Google Latitude is now live, a new service from Google that allows you to send your location to Google Maps and share it with friends via many mobile phones (not the iPhone yet, but that’s coming). Greg Sterling will have our own review of the service posted later today.
For now, you can explore it directly yourself now (or here via your moble phone). You can also use the service from your computer, though the instructions from Google on how to locate the iGoogle Latitude gadget don’t currently seem to bring it up. Instead, use this link, login, and then you’ll be prompted to install the gadget. I found so far that it wasn’t able to automatically detect my location using my computer, as promised — but you can set it manually.
NOTE: Our long review from Greg Sterling is now up here: Google Latitude Turns Maps (For Mobile) Into Social Tool.
