OK, a couple things on this without having had read the FTC's proposal.
1. Try telling that to WalMart who does a different variation of this but does it through credit card transaction data retention.
2. What does it matter? It will end up on Wikileaks anyway.
3. If you're out in the public domain (ie. The Internet) you have virtually no privacy, so what's it matter?
4. Is this going to be something kinda sorta like the Opt-In "Do Not Call" list?
