Free the Web
Rob the Geek has started an interesting Facebook group: Free Auckland Wireless.
Apparently, it comes as a result of discussions at KiwiFoo '08 - the conference where only the cool kids are invited, and everyone else gets jealous and calls them names (like "kids").
There's a blog (of course), and some interesting technology to discuss.
Personally, I'm running an open wireless network. Partly because of the golden rule, but partly because I just find it really convenient. The SSID is 'free wireless - dubdot.com', so people know it's intentionally open, and can contact me if they want. But, as I'm stuck in the middle of suburbia, nobody has.
