I completely disagree. In fact I find it worse when a link opens in the same tab and then I have to navigate back and find the place that I was at .vs. having to close a new tab I did not want. "And I think over a decade of user confusion and frustration resulting from target="_blank" backs that up." Do you have any links to to back this claim?
Update: found the paper - http://jeffhuang.com/Final_Branching_WSDM12.pdf
Here's the quote:
Users in the Chinese market nearly always branch [what the authors call opening links in new windows], a behavior forced by their search engines' default settings. Some people speculate [footnote for http://www.quora.com/China/Why-do-most-hyperlinks- on-Chinese-websites-open-a-new-window-tab] that this default started because Internet access is slower in China and so branching enables Web pages to load in the background. Others believe default branching is economically motivated as it allows a search engine to keep users on its site longer. However, a qualitative study of how Chinese users perceive branching versus backtracking would be interesting since their default action is opposite of that for the American and European users, who have been previously studied.
