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 http://disconnect.me

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.

  My wife is a Google Chrome user and she logs into Facebook and Twitter in an incognito window. Everything else she does in a regular Chrome window (which is set to delete all cookie when the browser is turned off). Another option would be to install a second browser and use it solely for FB/Twitter.

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

    "of course shared between browsers" Is it? Are saying that the flash crap doesn't distinguish between browsers/profiles? That's another very bad security problem with flash. For me, it's the final straw. I'm going to wipe flash from all my machines now.

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: http://online.wsj.com/article/SB10001424052748704281504576329441432995616.html http://online.wsj.com/article/SB1000142405274870428150457632... for some reason the Y! version trimmed some parts of the story
