One of the joys of my iPhone (and they are many and various) is its ability to easily find and join wifi networks - but only if they are open. I have learned to really appreciate people who leave their networks open as opposed to those who lock theirs.
In contrast, in my own home, I had allowed myself to succumb to general paranoia about security and locked my wifi network. Now, however, having real this Wired article I have decided to reverse that decision.
I wanted to do my bit to get back to the good old days of open access and "warchalking". The fact that I live in the middle of bloody nowhere means that the impact of this decision will be minimal but at east I am trying!
