I like it. But it still generates traffic to my network.
Well, it springs from an idea that works for me (as a user) without
being particularly good for the network. As I currently implement it,
using different email addresses, the spam I'm avoiding ends up sitting
on my ISP's mail server waiting to bounce. I was thinking that
widespread use of keys would eventually act as a deterrent to spam -
knowing that email to even a valid "public" key is going to be filtered
through an extremely selective spam filter ought to discourage people.
On further consideration, this may be a little naive of me.
