Facebook and Targeted Advertising

I think that collecting information about individuals through facebook to better advertise to them specifically is a good strategy. I feel sort of uncomfortable that people are collecting data about me when I am not even aware of it, but seeing as I agreed to it by signing up for facebook I don't disagree with it. There's no arguement that this is an invasion of privacy, because the user agrees to it. I don't look at my friends' profiles and entries as a source of advice on what to buy. I know it seems ridiculous, but I probably pay more attention to the advertisements at the bottom of the page than my friends' advice. I think that as targeted advertising on the web becomes more precise, the content of the web will become more important. If you are interested in skateboarding, and when you get online you see ads all about skateboards, I think it's just going to make it that much easier to find what you're looking for. I don't see targeted advertising as an invasion of privacy, but as a smart business strategy and helpful tool.
