The free WiFi/social networking space is getting crowded. WeFi is joining the ranks of FON and Whisher, introducing the ability to map WiFi locations and share that information via the service to put the spots on a map with a key. Users can also set up buddy lists to find out who is online and where they are located relative to a user's connection. WeFi is supposed to be different from FON and Whisher because it doesn't require specific hardware or a network membership like FON and is better at finding free locations than Whisher, according to WeFi's advisory board member Esme Vos. As Glenn Fleishmann at Wi-Fi Net News points out, the service could be problematic given the fact that more people are being arrested for using open WiFi access points without authorization.
