While not related to the topic exactly, the blur under the translucent header was so distracting I had trouble reading the article. Usually I can overlook stuff like this; I can't explain why it bothered me so much.
the problem really is that if you scroll you have enough variation between images and text it makes the translucent header function as a sort of blink effect, calling your attention away from what you're trying to read which is probably right up by where the header is blinking.
