Yup. That's my experience as well. I've been using Ghostery for a couple of years now, and I've noted that very few sites are benign when it comes to this stuff. Some blogs and sites like FR are trackerless, but most of them attach a posse of bots to your computer.
It’s really quite remarkable.....after just a few hours I could not believe how many trackers are on sites....truly astounding! Thank you for posting that link.
