I've always found it completely confusing that Slate, a publication that obsesses about life's minor and inconsequential irritations, is ITSELF a major offender in that category: every time you click over to the next page of an article, it takes you to a full page view and places you back at the top of the page. You lose your place! Heal thyself, SLATE.

I love this so much!
