> Gmail’s spam filters are Google’s weakest tech. At least I don’t know of anything worse.

I get a fair amount obvious spam coming through the filter, but the issue with any sort of classification is the tradeoff between False Positives and False Negatives.

The occasional False Negative causes a lot less damage (2 seconds to delete or report as spam) verses the damage of a False Positive (not seeing an important email for two weeks or ever).

I get a ton of false positives. The tech is truly lame.
