Should I turn Do Not Track on or off?
Do Not Track is a great idea, but when it comes down it, the technology has no bite. Companies can---and usually do---choose to ignore it and face no consequences for doing so. Despite this, you should enable the setting for the few sites that honor the setting.
Is it good to enable Do Not Track on Chrome?
Most browsers have a "Do Not Track" (DNT) setting that sends "a special signal to websites, analytics companies, ad networks, plug in providers, and other web services you encounter while browsing, to stop tracking your activity." Sounds good, right? Sadly, it's not effective.
