"I can count the spam I actually read in a year with one hand." This is partly because Gmail is good at classifying emails as spam/ham. But it's partly because it's more tolerant of false positives (ham sent to the spam folder) than you or I would be if we were tweaking our own spam filter. I occasionally check my spam folder, and there are usually some mailing list emails that I don't care about, but which I did actually subscribe to, and would have wanted to reach my inbox.
