Follow up
Just a follow up, I was referring to blocking ads and cookies, not to sites that barage users with 4-5 pop-ups, porno ads, etc. These are generally not LEGIT sites, but teenage boys or losers who can't find a legitimate source of income. Real sites seek to attract users, not **** them off.
Cookies, in and of themselves are harmless and the media has raised a lot of paranoia. Generally, when the media discusses technology, they are clueless morons and alarmists. Cookies DO NOT give out personal information, do not gather information off your hard-drive, etc. All a cookies is a variable (millions of which are used every second by all your programs on your system) that is stored remotely by the web server. There are INERT and non-executable.
Since web browsers are stateless (ie, ALL information about what you're doing is lost between each page request), a variable that exists between pages has to be used to retrieve state. This variable is the cookie. Cookies are absolutely needed to proper operation of most sites.
Example: You log on to TDR. Well since more than one person can share the same IP due to proxy servers, YBulletin makes a cookie using unique, randomly generated number. Every time your browser requests a page, YBB requests your id cookie. If it gets it, it looks on the server hard-drive for login information and validates you.
Banner ads, such as the ones used here, use cookies. Each banner places a unique number in a cookie in your browser. When you click the ad, the unique number is retrieved by the system that served the ad so it can quickly look up the ad in its database and redirect you to the correct web page.
Banner networks such as Double click can use the cookies to track you across several sites, but that doesn't mean they know "Bob Smith, who lives at XYXville, Anystate, SomeZipcode" visited A, B, C, F, X, Y and Z and purchased 42 magazines. Rather it knows user A874521010-29423 went to A, B, C, F, X, Y and Z, therefore we'll serve up ads that are targeted for the type of content at A, B, C, F, X, Y and Z.
My personal business's web site used Engage, Doubleclick and About.com for a long time. They never got any personal information from our users merely by serving them ads. They did, however, enable us to operate for a long period of time while we built up infrastructure for complete self-sufficiency. We are to another make/model what TDR is to Dodge turbo diesels but we did not have the benefit of a magazine to help keep the site operational. Without ads my site, along with a lot of other really good content/community sites, would have bitten the dust. That's something to think about... ...
