Wireless Network Get More Secure ... Duh

So, this ancient blog post stated that "80% of wifi networks [are] insecure" ( and points to a Slashdot interview with the author of Kismet). The date on the post is 08/20/2004; more than 2 years ago. And a funny thing happened - wireless networks actually gotten more secure! Nowadays one can't be certain that he would see an open wireless network whenever one sees a bunch of wireless networks somewhere...

As similar things happen in other areas of IT, the specter of security being done is being raised once again. But - guess what? - the answer is still NO.
