I really loathe authors who fail to understand the web concept, and try to outsmart the user. It's the user who ought to be in control, not the author. For me as the user, it's an 8 mm difference whether I want to open something in a new window or not: click the left button, or click the middle button.

By forcing opening a link in a new window, you rob me of a choice, which is quite user hostile.
