"Congress is trying to wrap its collective head around Amazon's new Silk Web browser. At a privacy hearing yesterday, Rep. Joe Barton (R-TX) expressed outrage at the way Silk's 'split' design can funnel all user browsing data through Amazon's backend servers. 'My staff yesterday told me that one of our leading Internet companies, Amazon, is going to create their own server and their own system and they're going to force everybody that uses Amazon to go through their server and they're going to collect all this information on each person who does that without that person's knowledge. Enough is enough.' Today came a similar shot from the other side of the aisle, with Rep. Ed Markey (D-MA) dashing off a letter (PDF) to Amazon CEO Jeff Bezos about the same privacy concerns. 'Consumers may buy the new Kindle Fire to read 1984, but they may not realize that the tablet's "Big Browser" may be watching their every keystroke when they are online,' Markey said in a statement."
