With many people worked up about whether or not Do Not Track will affect the freedom of the internet, it may be time for everyone to decide how it will really affect their searches. The ad industry, understandably, is arguing adamantly against the use of DNT. They believe that by ridding the internet of personal data collection, the way that tracking-based advertising works will become ineffectual. This may be somewhat true, but because there are so many other sources of advertising revenue, it is not going to seriously affect online ad sales.
Most browsers have chosen to move in this direction and Google Chrome—the biggest one to hold out—has announced that by the end of the year, they too will have a Do Not Track option for their users. At this point I think it is better for readers to consider what the impact will be on their personal life rather than getting wrapped up in the potential complications of ad agencies. At this point, it appears that no one is going to be hit by this act too seriously, but internet users may be able to retain a bit more privacy than they have experienced in previous months.
