The internet is a public place so you shouldnt be shocked that technology is used to track what you are doing , usually in the name of making you part with your money, I have a website here but that is seeing less and less of peoples money, A big part of that was when Amazon effectively stopped paying for referrals by creating a set of rules disqualifying email links , and sales to people who were already customers. Build your infrastucture then stop paying for it , a brilliant strategy.
Also The Cloud is being used as a storage facility , while I'm OK with it as a back up , I'm not happy with it as a first point of storage. Amazon and iTunes offer cloud storage , with the right to delete anything they deem not "licensed" . So when you use these facilities you effectively lose control.
Did you know that when you catalog anything with iTunes it writes to that file!! It should never do that as it effectively corrups the item, but it tries to and tries about 1000 times befor giving up,
Basically I dont need to be told that I need to be aware I'm in public when on the internet. It's Caveat Emptor and I dont need to be continually asked or reminded. I can install ad or popup blockers and switch cookies off aand everyone who uses the internet can do the same.
Thought the Bowie song was appropriate.
