Spam law
The CAN-SPAM bill has passed the House, and will likely be signed into law by the President soon. I predict that the bill will someday be viewed as something similar to the Anticybersquatting Consumer Protection Act — a piece of nationalistic legislation that provides little real protection against offshore bad actors. But it does not, at least, do very much harm to the interests of would-be commercial email senders — it allows anyone to send a commercial message that isn't misleading, as long as an opt out and physical address (?) is provided for the sender.
Spam is clearly a big problem, but it's highly unlikely that this bill will fix things. A great deal of spam comes from people who aren't subject to US laws. A second prediction: “trusted” email systems will become all the rage, and we'll soon be conversing only with those we choose as conversational partners. Maybe that's a fine solution. Maybe the internet shouldn't favor unsolicited, anonymous communications. And maybe digital certificates will finally be worth something to individuals.
