Yes, I think that this would be a good idea to have a browser option and or options in other applications as well that let one opt out of allowing ones browsing activities tracked and collected. The internet is becoming an ever larger source of threat to each persons identity and privacy. Though there are technical issues that would have to be overcome. I have no specific expertise in the coding for this. But "opting out" should be instituted to allow functionality and selectivity. "Opting out" should still allow one to otherwise interact on web sites and with businesses of ones choice. Currently many web sites or web fuctionality will not work with out allowing cookies. Many browsers currently allow settings that include blocking of cookies, but then you basically can only view a site but can not make purchases, send forms like this one, or do on line banking, etc. with out cookies being "turned on". That is an issue that needs to be looked into as well. Therefore opting out of data tracking must be set up to still allow wanted interaction between consumers and web sites. Also it should be selective so the consumer can choose to allow some data tracking to occur with sites one wants to share information with. For example I do not mind getting purchasing suggestions from Amazon due to my previous purchases as some times they suggest CDs, DVDs, and books that I do find interesting that I otherwise would not know about. I prefer these seggestions being shown while viewing Amazon and not from being sent emails. Aslo the "default" selection for all websites should be not to share information with other businesses or associates. Currently unless you are very careful you find your email address spread everywhere.
