Definitely. I rarely bother with Facebook any more, but when I want to share something, copy and paste is not hard. The "social buttons" don't solve a problem, IMO.
actually, what started the decline was the very subject of this article. I don't like Facebook watching where I go, and I started putting Facebook in another browser; naturally, I'm on Facebook less because it's harder to get to.
In theory, using a separate browser is not adequate protection from tracking. The Flash Player's "Shared Objects" (aka Flash cookies) are stored in a common directory, so the same Flash data is accessible from any browser running as the same user. I do not believe Facebook's tracking is this nefarious, but the method would be quite easy to implement.
