Here's today's example: http://www.wired.com/rawfile/2012/11/robert-burley-disappearance-of-darkness/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+wired%2Findex+%28Wired%3A+Top+Stories%29
The experience is always the same. I view the first image, click to go to the next image and CLANG! ZING! HISS... The entire page refreshes (slowly) to display the next image. This process continues with every image. I don't remember the last time I looked through an entire set of images on their site because of this. Incidentally, this happens with their textual content, too.
Until now, I've made a mental note to try to avoid their site in the future. However, after reliving this experience again today, I thought I'd mention it here to make a brief statement about presentation.
To all you aspiring developers who share your work here on HN, use the constructive feedback you receive to your advantage. If a visitor tells you that your site locks up their browser or that something isn't displaying correctly, don't take it as an insult; no matter how much work you've put into it.
It doesn't matter how great your content or how useful your product, if you don't pay attention to your presentation, you are wasting your time and, more importantly, my time.
