This week’s splogstorm and the endless flood of email spam are two symptoms of the same disease. When you allow people to add content to the Net for free, the economic incentives to fill all the available space with with spam are irresistible, and fighting back is difficult, maybe impossible. This works because, while the payoff per unit of spam is low, the cost is zero. Well, we can solve all these problems at once. It wouldn’t be free, but it would be cheap and it wouldn’t be that hard. It’s called “Internet Stamps”.
No offense meant, but Internet Stamps sound a little to close to an "Internet Tax" for comfort. While CACert doesn't allow much room for the anonymous side of this idea, as Bill de hÓra recently stated "Anonymity, last time I checked (yes, I did check) is not a neccessary feature to make the web work." Extending from this notion the idea behind CACert is to use existing SSL certificates to ensure via positive identification that you are who you say you are. Adding to this, any email client worth its weight in bits already supports this standard, so its pretty much zero-entry to gain wide spread and immediatte support. Again, not much room for anonymity but as Bill de hÓra once said (see same statement and link from above :)
