Motivated by this thread, I just checked my personal account (gmail, email address hardly publicized at all) and my business account (GAE business, email address widely publicized). In the interest of balance, my anecdata is that the gmail anti-spam filters work very well for my two accounts. No false positive spam at all in the personal account, and only a few dozen spam over the last several weeks. One false positive spam in the business account out of the several hundred I bothered to check before I got bored (I've close to 800 spam over the last few weeks) - and that false positive is something I could easily have ignored. Works for me, FWIW, YMMV and likely does.
