Has anyone else noticed the change in spam patterns?


Traditionally my spam has had crazy subjects such as this one:

H0liday $pecials va|ium, VIC0DIN, xanaax, Cia|is secular qgzz gelv knzzeg


However, I've noticed in recent days, subjects such as these:

Equally sensless, yes, but maybe someone has developed smart filters that look for non-words? So now they're sending random real words as subjects? And this is supposed to somehow entice me to open the message?

As someone with 12,752 spams in my junk mail folder (and upwards of 20,000 addresses in my junk senders list), I have plenty with which to analyze patterns. I keep thinking I'll get around to buying some anti-spam package and will need some "sample junk" to setup the program.
