Spam, beginning to drift

Spam seems to be beginning to drift. Not necessarily drift away, but from a volume and an importance point of view. My impression is that the CAN-Spam laws have caused porn spam to virtually disappear (at least in my sphere of influence) and much of what we get is severe repetition. In my opinion, this is a good thing - spam is becoming less of a viable revenue source. The less revenue associated with it, the fewer players, and eventually a falloff in businesses that support it.
