And it's really not anything like taking things back to the stacks, and going back to the stacks to retrieve it again. Clicking on the "Back" button isn't much different then a closing or minimizing a new window to get to the old article. Really need to keep them both up? The browser has you covered.
As previously addressed, every modern browser affords the user with the ability to open in a new window/tab quickly and easily if that's what you want -- no need to even go through the trouble of right click and using the menu, you can easily shift/ctrl/alt click or use the mouse3 (middle) button. Opening other sites in the same window may distract from the flow of reading/viewing forums/topics... but opening other sites in a new window distracts as well; it's sorta the point of following a link to begin with - to view something else. This is inherently distracting from the forum or topic you were reading previously, but it's the foundation on which the www is built.
Obviously it's up to every individual web master to decide what they want their site to do. Frankly I find a site that forces me to open a new window to be annoying. If I wanted it in a new window, I'd have opened it in a new window.
One person's "arbitrary" is another person's "clear demarcation".
Again, I offered the caveat that if an external link loads in a new window, it should have a way of alerting the user to that beforehand, so they can take action to load it in the same window via right-click choice. I see all this as a matter of not surprising the user, whether the webmaster decides to automatically open new windows for external links or not.
While this automatic opening of new windows for external links is annoying to some (granted), it is not annoying and indeed welcomed by others, especially judging from this discussion. Can't please everyone.
