Mozilla has a petition asking Facebook to stop tracking people's browsing off the site unless they opt in to it. Frankly I think the solution is to remove the ability to track people across sites from the web entirely, but I signed the petition anyway. Facebook has taken a huge hit to their reputation, so now is a good time to be putting pressure on them to change their ways.
@seanl It's laudable but an effort in vain. Asking Facebook to stop tracking users is like asking Tiffany's to stop selling diamonds.
@mindnmotion Eh I don't know about that; they already get a huge amount of data from their users voluntarily and have expressed concern internally about the "creep factor" even if they are often naive about what people will find creepy.
@seanl I failed to consider the press value of Mozilla's actions.
