The press has quite a bit of buzz about the new MailBlocks spam eliminator service. It's a subscription service $10 a year, additional two years free for early adaptors. The price is obviously right for moving over masses of people, and it has some content-minded concepts, such as building portfolios of trusted content providers. Main two problems: you have to use their email address (so much for serious business use) and it requires the user to build the filters of trusted suppliers from scratch. Worth watching, and we will, but mostly for the trends in how it may use email to amplify trusted content relationships.
