Actually, I was quite interested to notice recently that I don't seem to get that much spam any more. There are apparently only 16 emails in my spam folder from the last 30 days. I'm not particularly careful with my email address either.
I have fairly a boring Spamassassin configuration on my mail server, and I don't get a lot of spam reaching inbox.
What I have noticed, however, is that I am now getting more and more telemarketing phone calls (robo calls) on my cell phone than I am spam hitting my inbox. It's reached the point where I keep my phone on silent all of the time because I get 5+ robo calls each day.
You must have a good filter. I get hundreds of chinese spam emails every month (which get moved to the spam folder automatically) since I made my address public on a couple mailing lists.
