Google has announced that end users will be allowed to download a plug-in for their browsers to stop sites using Google analytics from tracking what they do and where they go. Google has suggested that the initial take-up of this option will mean around a 10% loss of traffic being reported. If you use the Analytics service, and you see a drop in activity, It may be because of this plug in, and not because of a drop in visits.
Personally, I think this number will get much higher as the knowledge of this plug-in permeates the Internet. You may need to start thinking of how much reliance and importance you place on the data you get from this service.
