I agree that most of the web is probably ignorant at best of most security vulnerabilities. But, keep in mind that firesheep is not exploiting a new vulnerability, but an old one that has been known about since probably early 2000. Firesheep is new in that it is automating the work of other programs (which were admittedly a little less user friendly).
