I don't know about Twitter or Pinterest's tracking, but I do know that most ad networks will also track you as much as they can between all the sites.

There are several products that help deal with this, but they don't get nearly enough attention. The one I'm familiar with is PrivacyFix [1], but there are several others that should also be investigated if this matters to you.
