It's not really "dangerous", it is just that you give a bit more information to FB/Twitter/$SocialCompany than you thought you would. While, I usually logout of FB or Twitter, I have a few adblock rules to block them on other webpages. It works fairly well... If I want to like and share, I believe I can do it manually...

You could add the EasyPrivacy list ( http://easylist.adblockplus.org/en/ ) to your adblock subscription.

They couldn't have published a more obvious story. Anyone with any sense doesn't log into either service and you don't need to be logged into either service for them to track you. It's amazing what freely available information (your IP, the sites you visit, etc) can do to help turn you from an aggregate anonymous identity into a fairly well "guessed" identity. And since webmasters carelessly litter their sites with t…

I agree with the other commenters that "common sense is remarkably uncommon." Yes, once you've grasped how web cookies and iframes and other mechanisms can be combined to track you across web sites, it is obvious that Facebook can track you even if you don't click the "like" button.

But most people don't have this level of understanding, and I'd say that Facebook goes out of their way to make this non-obvious. So yes, you're right, but also yes, this type of article is relevant. You probably read something like this once, and it was a revelation for you. Now others are getting their tall, cool, glass of reality.

No idea why you're getting downvotes, unless people equate your comments slightly dismissive tone with being non-contributory. Personally, I've seen far worse, and you have some useful tips embedded in the comments, so as far as I'm concerned your comment is a win. Thanks.

You might want to consider amplifying on your methods of maintaining your privacy, others may find a more detailed set of instructions helpful.

From what I gathered in the article, logging out doesn't solve the problem. The cookie works if you've logged in anytime in the last month

It's obvious to you, dear HN reader. But please step out of this little bubble, and ask random strangers on Main Street (or whatever the equivalent is in your domicile) if they know how the "like" button appears on their web page; if they know what HTTP Referer means; etc.

I'd wager that 95%+ of the users on the 'net wouldn't know the implications of these buttons.

This doesn't seem to be the full story. If I log out of FB I still have multiple cookies for the .facebook.com domain (e.g., c_user, which seems to contain my user id). The like/comment/etc. 'widgets' are served from facebook.com, so presumably they are still tracking me. Don't know why this article didn't mention Ghostery or http://disconnect.me

Brian Kennish, who is mentioned in the story, is the author of disconnect. He helped the WSJ do the research, here is the original article:

for some reason the Y! version trimmed some parts of the story

You could also use multiple profiles (at least in Firefox), one for browsing around and one for social network sites. In that case there will be guaranteed no cookie cross-pollution as the sites are completely isolated from each other. Just logging out is indeed simply ineffective.

If only... Facebook uses a Flash LSO, which is of course shared between browsers.

Also, Facebook uses a Flash LSO. You have to clear that to really be logged out.

Many thanks, I didn't know about this one.

Which is why I said that I used adblockplus rules for this.
