On a similar note to this, I generally like to open links in new tabs, so that I can refer back to the original page without losing my place, or to refer to the linked content after I finish on the current page. This does not work when you are using styled buttons, or pages which rely heavily on JS/AJAX to do their thing. Inevitably in this case, I must navigate away from the original page, look at the content and then use back, hoping that I return to the correct location.

Notable examples of this include the Facebook "Show more comments" link, g-mail's email links and "Add to Cart" buttons which redirect away from the product page.
