You may not like to hear this, but I've had several Gmail accounts over the years (including some domains hosted by Google Apps, if that counts), and I have never.... repeat: never ... seen a single spam come to any of those accounts. By contrast, when I had Yahoo and Hotmail accounts (the latter of which had addresses that I never shared with anyone or any company), I got spam. Go figure.
Why wouldn't I like to hear that? It's good to know that others are seeing the same downtrend in spams making it to Gmail. The overall label is down, though I'm getting a couple more inbox. I was starting to wonder if there was less spam because some of my old forwards into the account were broke.
I thought it might lessen your excitement over your spam being "down" to 385 if you found that others are getting none at all. I didn't want to rain on your parade, but mentioned it anyway for comparison's sake.
