I think publicity is no longer something that need to be sought out. However, some of the anti-bitcoin propaganda that is becoming more and more prevalent does need rebuttal...in a rational, level headed manner. Predictably, the propaganda machine is cranking up and trying to associate bitcoin with various illegal activity. A simple counter point to that is to describe to people how insane you'd be to use bitcoin for illegal activity as every transaction will be recorded permanently and available to anyone for analysis. Most criminals likely do not possess the skills that would be necessary to hide your tracks in the digital world. Criminals and tax evaders would be wise to steer very clear of bitcoin.
There are criminals going about their business as we speak. These criminals are already savvy enough to do what they do without getting caught and Bitcoin won't change a thing to it. As for wannabe criminals that thought they might get away with it now thanks to Bitcoin, 99% of them will get caught, since this is but a case of PEBCAK.
