Spam solution? Perhaps not.
Lots of really good commentary regarding the GoodMail solution and Esther Dyson’s op-ed piece in Dave’s comments. Unfortunately, aside from a brief visit from GoodMail’s founder, it’s been pretty one-sided.
This does have the feel of an answer for the privileged. For what it’s worth, I’m all for a better spam solution, but there are alternatives that can make it more difficult for the true spammers without making the rest of us bear the burden. SenderID, for all its weaknesses, comes to mind.
