True. And I also suspect that either because of Yahoo's larger
userbase or because they have walled themselves into a particular
system architecture there is a sizable delay between when I mark
something as spam and when yahoo's mx servers start treating similar
incoming email as spam.
As hserus pointed out, google's server farm is of legendary
proportions. And the anti-spam guys at Google are some of the smartest
people I have worked with. Both of these mean that there is a smaller
delay between when I mark something as spam and when similar mails
start getting detected as spam.
I don't think Yahoo's problems are purely technical in nature. Some
very smart people work at Yahoo. I suspect that making radical changes
to a mature service is not very easy. And that is what is keeping
Yahoo from being better at spam detection.
