I would like to propose that we, as technologically literate people, start to separate the concepts of encrypting your WiFi signal, and sharing your WiFi signal.<p>Encryption has true security benefits, primarily the prevention of HTTP session hijacks via tools like Firesheep.<p>You can still share your network by simply putting the password in the SSID. Name your network "Password is 12345" or something. Encryption protects against Firesheep even if everyone knows the password.
